Bug 127629

Version:            (using KDE 3.5.0, compiled sources)
Compiler:          gcc version 3.4.3
OS:                Linux (i686) release 2.6.15.4-0

When I am using the 'Image View' mode in Konqueror, sometimes when I navigate between directories using the filesystem tree, Konqueror crashes. It seems to happen if it is generating thumbnails for one directory when I click on another directory (in the tree) to navigate to it. It only happens rarely, but if I get two folders and switch between them rapidly, without giving it a chance to generate all the thumbnails, then I get a crash within a minute or so. The backtrace is as follows:

Using host libthread_db library "/lib/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
