calibre 6828 bus error on launch

[fiver22]

Hiyo,
I run Linux (Crunchbang converted to Debian Testing

fiver22@m0nster:/home/fiver22  $ uname -a
Linux m0nster 3.12-1-amd64 #1 SMP Debian 3.12.6-2 (2013-12-29) x86_64 GNU/Linux)

I've never had an issue w/ Calibre since I started using it ages and ages ago -always on linux. I use the defauly (/opt) location:

sudo python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read()); main(install_dir='/opt')"

However when updating to latest (The latest release of calibre is 1.19.0.) using the above method and the default install location all went well until I tried to launch calibre (I typically use Synapse as a launcher and have never had an issue before) -this time NOTHING happened so I ran

 calibre -v

from the terminal. This launched calibre with the following output

 fiver22@m0nster:/home/fiver22  $ calibre -v
usbmuxd_get_device_list: error opening socket!

So, I'm looking for advise on how to fix or how to provide more useful info.
Thank you!

Run it as calibre-debug -g

Hello again,
I just tried running it via synapse launcher (http://launchpad.net/synapse-project) again -and this time it calibre launched without issue.
I am posting the output you asked for in case it tells you anything:

fiver22@m0nster:/home/fiver22  $ calibre-debug -g

I am running usbmuxd 1.0.8-2 from http://packages.debian.org/jessie/usbmuxd
I see it's used to access the iPhone/iPod Touch via USB but am not sure why it's giving me trouble -as far as I know I've always had the package installed but where I'm running Testing it could have come in recently, I ran

ls /var/lib/dpkg/info/*.list -lh | grep usbmuxd
-rw-r--r-- 1 root root    0 Dec 27 22:16 /var/lib/dpkg/info/libusbmuxd1.list
-rw-r--r-- 1 root root  208 Dec 27 21:06 /var/lib/dpkg/info/libusbmuxd2.list
-rw-r--r-- 1 root root  303 Dec 28 00:05 /var/lib/dpkg/info/libusbmuxd-dev.list
-rw-r--r-- 1 root root  454 Dec 27 21:08 /var/lib/dpkg/info/usbmuxd.list

but I'm certain I've used calibre since those dates without issue.
Again, calibre is now launching normally but I suspect /something/ is a bit off -mind you I've never run calibre in debug mode so /maybe/ it always threw that error.

Is there any other information I could provide to you?
Thanks for your time.

I see nothing suspicious in that debug output. usbmuxd failing shouldn't prevent calibre from running.

[fiver22]

Fair enough. Thank you for your time and thank you even more for calibre -it is by far my favorite f/oss!
I've donated a few times and hope others do the same -you deserve it.
