Bug ID: 383086
Summary: KDevelop crashes whenever I try to access disk (save
or open file
Product: kdevelop
Version: 5.1.1
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: jacoposchiavo...@gmail.com
Target Milestone: ---
Application: kdevelop (5.1.1)
Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-28-generic x86_64
Distribution: Ubuntu 16.04.3 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I have rebooted my pc, the only running applications were Dropbox, Plasmashell
and Yakuake. I have tried to remove, purge and clean all the packages and
reinstall from scratch the application, but the error still is here.
- Unusual behavior I noticed:
The application can be opened, a new file created and written. Whenever I try
to save, the application crashes and closes. The same happens trying to open a
file saved on the disk. The file is not currupted.
- Custom settings of the application:
Nothing worth noting: now it is completely freshly installed.
The crash can be reproduced every time.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
