Description fantaz 2016-06-30 08:52:01 UTC 
Application: kdevelop (4.7.3)
KDE Platform Version: 4.14.21
Qt Version: 4.8.7
Operating System: Linux 4.6.2-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160626) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

The Kdevelop 4.7.3 is not vanilla version, since I'm using patched version installed from the Tumbleweed repository. Nevertheless, the Kdevelop crashes every couple of minutes when I'm in the middle of code editing.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

New crash information added by DrKonqi

kdevelop (4.7.3) on KDE Platform 4.14.24 using Qt 4.8.7

- What I was doing when the application crashed:

Typing a variable name and Kdevelop crashed right before offering completion.

kdevelop (4.7.3) on KDE Platform 4.14.24 using Qt 4.8.7

- What I was doing when the application crashed:

I've just typed a variable name and the automatic word-completion crashed at the last letter.

The error occurs in every case, the Kdevelop IDE is utterly unusable.

New crash information added by DrKonqi

kdevelop (4.7.3) on KDE Platform 4.14.25 using Qt 4.8.7

- What I was doing when the application crashed:

I edited code and Kdevelop crashed just before I expected the auto completion to propose an enum name. The crash can be reproduced by entering the same text at the same file at the same location.

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!
