Bug 420366

Application: konqueror (5.0.97)

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 4.15.0-97-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
When trying to open bookmarked local directories, current konqueror (5.0.97) reproducibly crashes. We see that on different machines, i.e. corrupted bookmarks are unlikely. 

Bookmarks are therefore no longer usable when using konqueror as a file manager. This is particularly unfortunate, since konqueror with its multi-split window flexibility would be the much more powerful file manager (compared to dolphin)!

Distribution KDE Neon User Edition, at current patchlevel.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
