Bug 174578

Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I use gwenview to view images stored in a zip file. When I use "Go Up" to return to the folder level (using either alt-up, the up tool I added in the toolbar or the "up" item in the "go" menu), gwenview *always* crashes, with the following report from the kde crash handler:

A Fatal Error Occurred
The application Gwenview (gwenview) crashed and caused the signal 6 (SIGABRT).
...

Using the "show details" checkbox, I have this backtrace:

... (omitting the useless messages "no debugging symbols found")
