Description Marcus Harrison 2012-11-06 12:03:12 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.2
Qt Version: 4.8.2
Operating System: Linux 3.6.3-1.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
- Custom settings of the application:

I have configured a folder view widget on one of my activities to point to a fish:// folder that has authentication information stored in KWallet.
If that activity is running when I log out, logging in causes plasma to crash. However, if that activity does not have the remote folder view or is not running when I log out, logging in does not cause plasma to crash. Plasma does not crash when it restarts. This may be due to my laptop not being connected to the network until some time after plasma has started.

Additionally, plasma asks for the authentication information for the fish:// folder, but fills the dialogue box in from KWallet automatically, instead of simply logging in.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault

Comment 1 Christoph Feck 2012-11-06 14:48:08 UTC 
Caused by nested event loop in QOAuth (see #37).
Comment 2 Martin Flöser 2013-05-29 13:23:04 UTC 
Thank you for this crash report and helping to improve our software. Unfortunately we were not able to work on this specific report yet. Nowadays the version this crash was reported against is no longer maintained and this makes it very difficult to work on this report as the source code might have changed and the information in the backtrace is no longer valid. 

Also it is quite likely that this problem got fixed in a later version. Crash reports are very often reported multiple times.

If you are able to reproduce this crash with the latest version of KDE Plasma (4.10.3) please reopen this report and adjust the version information in the dropdown above and please also include a new backtrace as generated by the crash reporting tool. Please also make sure that the steps on how to reproduce the crash are precise and correct. Thank you!
