calibre 2.0 strange crash

cybmole · 08-23-2014, 07:29 AM

don't think I've ever reported a calibre crash before. win 7 64 bit.
I clicked the system tray icon to restore main window & it simply vanished.

So then I tried to start calibre from start manu - nothing happened.

task manager shows 2 instances of calibre.exe running and will not stop them.
tried kill process, kill process tree - nada,
am going to have to log out or reboot. is there anywhere i should then look for a log to post here ?

update: everything on PC was working fine except that I could not run calibre, tried to log off, PC hung , needed hard reset. seems OK now, cannot find any error logs to post....

and another one- this time I put PC into sleep mode, while calibre was running ( idling). not other programs running I think
PC goes to sleep then 1 second later the CPU fans go to 100% & I have no control. it will not wake. have to hold in power button until it shuts down.

I am wondering if Qt5 & win 7 64 bit are not playing nice together ? MY PC is usually ultra reliable & the only recent install was this calibre upgrade to 2.0 ?

I ill trigger sleep again in a minute & see if I can reproduce....

Sleep works fine here. Win7 Pro/64 and Win8.1/64.

I don't use the systray icon.

There are some issues with qt 5 and system tray icons, but I thought they were only limited to linux. See for example: http://stackoverflow.com/questions/2...qt5-linux-lxde

That said, I cannot reproduce any system tray icon related crashes on my windows machine either

I turned on the systray icon on my win 8.1 machine (the one I am using at the moment) and it seems to work fine. I tried both sleeping and hibernating, and neither "broke" the tray icon. It did move to the "hidden icons" section after a sleep, but it worked fine from there. I will leave it on to see whether something happens in the future, and I will try it on my Win7 machine when I next use it.

I can not reproduce it on my Linux Mint 17 64bit system with 10 sleep wake cycles--with calibre on system tray and open on screen.

I have just installed 2.0 (was running 1.48) and it crashes every time I run it

I ran the repair option and it still crashes.

Removed 2.0 and reinstalled 1.48 and it runs fine. I always install the latest release and have not had any problem upgrading until 2.0 was released.

My guess is that there is a bug of some sort in the just released 2.0 that is causing it to crash.

Is this a known problem and will there be an update anytime soon for this? I noted that others have had the same problem in the last day or so.

FYI - I run XP with all updates and service packs installed and have had NO problems until installing Calibre 2.0.

Qt5 is known to have some issues with XP. Best thing you can do is to upgrade away from XP and get a Windows that works better with Qt5. Both Windows 7 and Windows 8.1 are faster then Windows XP.

Not sure if this is related to your problem but when I started playing with the Calibre 2.0 betas, I had a couple of odd issues. Basically, I ended up taking notes about all the plugins I had installed, settings, etc. and then uninstalling Calibre and deleting all the Calibre directories (program and user data) except the library directory. Installed Calibre and the problems seem to have disappeared.

i was not able to reproduce the sleep issue, or the 1st crash - not yet anyway.
i have a fanless graphix card so the fan noise must have been cpu fan going to 100%, maybe some glitch not related to calibre but i reported it as is was my 2nd crash after upgrading to 2.0. my CPu fan hardly ever revs up in normal use. even if I drive the cpu hard with book or video conversions. I only usually hear it for a couple of seconds at boot up as all Dell PCs start by giving the fans a brief blast
