Description Piotr Mierzwinski 2012-06-19 10:25:50 UTC

Gwenview 4.8.4 run on KDE 4.8.4.
First start of application (no apps data). I click on "Root" in panel "Places" (right side). It made crash. Each next execution of Gwenview made crash, because (unreadable) directory "Root" has been saved in Recent directories and Gwenview used it when starts. I must remove ~/.kde4/share/apps/gwenview directory to Gwenview not crashed when starts.

Reproducible: Always

Steps to Reproduce:
1. Login to common user
2. Remove directory: ~/.kde4/share/apps/gwenview
3. Execute application
4. Click on Root (in "Places" panel)
5. Application crashes (shows notification dialog)
Actual Results:  
Application crashes.

Expected Results:  
Application shows KMessageBox contains error description.

Distribution created by SuseStudio (http://susestudio.com).
Used following repositories: KDE:Release:48 12.1, KDE:Extra:Release:48

System not installed on hard drive, but running from pendrive (wrote like disk image).

Please paste the backtrace shown by Dr.Konqi here if it crashes every time.

And what does " (unreadable) directory "Root" " mean?  That entry should take user to "/" .

Sorry, my mistake. When Gwenview crashed I thought, that 'Root' indicates to the user "root". Common user have no read permission to this directory and that's why application crashed.

And one more thing. I made the test again and everything worked fine. Hmm. Something wrong. I'm sure that Gwenview was crashed. I remembered that it was the first start of KDE4. That's why I made the test one more time, but before I removed configuration directory (.kde4) for kde4. Below steps I repeated two times and each time application crashed.

Steps to Reproduce: 
1. On "Login screen" switch to the text console and rename directory: ~/.kde4. Example:
    mv ~/,kde4 ~/.kde4_old
2. Back to "Login screen" and login to common user
3. Execute application
4. Click on Root (in "Places" panel)
5. Application crashes (shows notification dialog)

Shame that no comments can be edited. I put a comma instead of dot. Step one should looks like that:
1. On "Login screen" switch to the text console and rename directory: ~/.kde4. Example:
mv ~/.kde4 ~/.kde4_old

Thanks for your feedback. 

Thread 1 (Thread 0xb432daa0 (LWP 5228)):

So this is another crash introduced  by the problematic kdelibs + soprano combination for the KDE SC 4.8.4 release. See bug 301474 and bug 301453.
