Bug ID: 385209
Summary: Several applications started crashing when trying to
open standard dialogs
Product: kdialog
Version: unspecified
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: general
Assignee: br...@frogmouth.net
Reporter: florin.jurcov...@gmail.com
Target Milestone: ---
Application: kate (3.13.3)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-132-generic i686
Distribution: Ubuntu 14.04.5 LTS
-- Information about the crash:
Simplest way to reproduce - the attached stack trace is from such an operation:
- open kate
- type something into the file created by default
- File -> Save as ...
Expected: save as dialog appears
Actual: Kate segfaults
Vlc crashes similarly on File -> Open file ..., Chromium web browsers does not
crash trying to select a picture for upload, but I do get the KDE crash
reporting window instead of the file open dialog.
If I try kdialog --msgbox "something" from the command line, it works as
expected.
The crash can be reproduced every time, in every application.
I tried sudo apt-get install --reinstall for several packages, the various
applications and kde-baseapps among them, but it didn't help.
This only started happening since a few updates ago, but I can't pinpoint the
exact point in time.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
