Description Christian Reiner 2014-03-10 12:37:14 UTC 
Application: kdevelop (4.6.60)
KDE Platform Version: 4.12.3
Qt Version: 4.8.5
Operating System: Linux 3.11.10-7-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I often use projects stored on a remote server which I can access via various protocols. I like to use the sftp protocol, I am able to configure a project inside KDevelop using an sftp location as base folder for a project. Most likely this relies on a kio slave. 
When working with such a project, KDevelop often crashes. 
One thing can be reproduced in all attempts: KDevelop crashes when trying to open the project configuration. A backtrace of such crash is attached. 

- Custom settings of the application:
Project using an sftp location as base folder

- Packages: 
These are standard packages from the official openSUSE OBS repository on a X86-64 platform using KDE-4.12.

The crash can be reproduced every time.

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

The crash seems to happen inside a plugin we dont normally ship: kdevelop4-plugin-upload.

Can you try to unload that one and check if KDevelop is more stable without it?
Comment 2 Christian Reiner 2014-03-10 13:11:19 UTC 
After uninstalling that "upload" plugin I still got a reproduceable crash, but at a different position now (obviously). I removed another plugin ("sql"), after that I am able to open the configuration of an sftp based project. 
Ok, thanks for the hint, this shows where the problem llies and I do understand that this is nothing the kdevelop team can offer assistance. 

My problem: without those plugins certain features are missing in kdevelop which I require for some projects (I work on several projects at once). So this is not really an option since using external tools for those tasks would painfully slow down my development speed. After all there is a reason why one wants to have an "integrated development environment"...

I do understand that those plugins might be considered "3rdparty" or "unsupported". Nevertheless they add valuable features to kdevelop, making kdevelop a much more interesting product.
Comment 3 Niko Sams 2014-03-10 13:33:56 UTC 
upload and sql plugins should work, but probably you have to rebuild them.

If you still have issues with them please report that directly to me....
Comment 4 Christian Reiner 2014-03-10 13:45:54 UTC 
Hm, OBS rebuilds all packages automatically if dependencies change (are rebuilt). Since I upgrade on a regular base I should have freshly built packages more or less all the time...
Comment 5 Christian Reiner 2014-03-10 20:35:34 UTC 
Sorry, to say so, build I have no success: I created a private repository for kdevelop on OBS and forked the packages. That way I can guarantee to have freshly built packages. 
Unfortunately I get exactly the same problem: a reproduceable crash when trying to open the project preferences. The backtrace looks exactly the same.
Comment 6 Christoph Feck 2014-04-21 13:53:02 UTC 
Christian, is this still an issue with a recent version? If yes, please add a comment, or reopen the bug.
Comment 7 Christian Reiner 2014-04-21 13:55:56 UTC 
I'll have to test that in an explicit manner. I disabled two plugins, since I never got them to be usable in my situation. Therefore I preferred to skip their features and handle those tasks in a separate manual manner. Not really the idea behind an IDE, but hey, it is more important to be able to use it ;-)
I will reopen this once I come around testing this again.
