Calibre constantly crashes

[F.W.]

Hello,

I have used Calibre for years now without any troubles, but am now facing a situation I have never experienced before. After updating from version 2.47 to 2.48 I can no longer use Calibre as intended, as it constantly crashes. Although I still manage to launch the programme, it freezes as soon as I perform simple tasks like adding a book to my library and then crashes. Viewing a book is possible though and the library maintenance check showed no errors in the library database.

Updating to version 2.49, repair install as well as a complete removal (including the library folder) and new install have not solved the problem for me. The programme crashes the second I try to add a new book to the library.

Here's the debug log

calibre Debug log

Interestingly, the above mentioned problem does not occur with Calibre Portable. My backed-up library works perfectly on my USB-drive.

Any ideas what I could do?

Thanks, Kovid, for the quick response. Indeed, SpiderOak (which I have installed a long time ago but never ever used) was the culprit. Why the freeze / crash of Calibre only occurred just now, I don't need to know. All that counts is that everything works nicely again!
