Description António Oliveira 2010-05-28 17:20:47 UTC 
Application: kdevelop (4.0.0 (using KDevPlatform 1.0.0))
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
While editting a header file, I entered a '.' which might have triggered autocompletion, then clicked (to open) the Documentation view.
This led to the first crash.

Now, everytime I try to start Kdevelop and answer yes to "recover" the unsaved header file, kdevelop crashes with a SEGFAULT.

cheers,

The crash can be reproduced every time.

 -- Backtrace:
Application: KDevelop (kdevelop.bin), signal: Segmentation fault

Comment 1 Andreas Pakulat 2010-05-28 18:13:46 UTC 
please run kdevelop in valgrind:

KDEV_SESSION=blah valgrind --track-origins=yes kdevelop.bin

and reproduce the issue. Then post the valgrind log.
Comment 2 António Oliveira 2010-05-28 18:20:59 UTC 
Humm,

unfortunately, in order do proceed the work I was doing, I canceled the file recovery on startup, which sent the problem away and now I'm unable to reproduce it :-(

If I come across this again I'll do as requested.

Is that 'blah' just a placeholder for some KDEV_SESSION value, or should it be input exactly as shown?

Thanks.
Comment 3 Andreas Pakulat 2010-05-29 02:10:49 UTC 
To get the recovery dialog you'll have to use the session id of the session that was shutdown unclean (i.e. kdevelop crashed).

Dear Bug Submitter,

This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days, the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information.

For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging

If you have already provided the requested information, please set the bug status as REPORTED so that the KDE team knows that the bug is ready to be confirmed.

Thank you for helping us make KDE software even better for everyone!
Comment 5 António Oliveira 2018-09-26 20:47:49 UTC 
Hi,

Even though it feels like I'm speaking to a machine [ :P ], I'm just taking the time to express that this is either too old or already fixed to deserve any further attention.

I'm taking the liberty to set this as Resolver/Worksforme. Hopefully it won't steal any precious time from the kdevelop jedis.

--cheers,
