Comment 1 Sven Brauch 2015-10-13 13:06:24 UTC 
Can you reproduce this crash? What exactly were you doing to make this crash? It looks like a specific set of actions is required to trigger this.
Comment 2 Daniel Stöckel 2016-08-28 07:33:36 UTC 
Hi, I am also experiencing this crash. You can reproduce it with the following steps:

1. Run a unit test
2. Remove the "Run" toolview
3. Run the unit test again
4. KDevelop should crash in OutputView::changeTitle with this == 0x0

Here is my backtrace:

Application: KDevelop (kdevelop), signal: Segmentation fault

Comment 3 Sven Brauch 2016-08-28 10:18:47 UTC 
Indeed, thanks for the instructions. The tool view does not seem to be removed from some list somewhere when clicking Remove, so it is still returned (instead of being re-added) on the second run. This also happens for the native app job and I guess all output jobs, they just don't crash but instead just don't show anything.

I poked around for quite a while now, couldn't figure out how to fix it or what happens exactly. :/
Comment 4 Sven Brauch 2016-08-28 10:22:16 UTC 
The severity of the bug is somewhat reduced by the fact that it basically never makes sense to remove the Run view.

Hi, I tried reproducing this bug, but was unable to. When removing the run toolview and re-running the test everything seems to work. I.e.: a second tab is added to the now hidden run toolview and reappears when re-adding the toolview again. I have set the resolution to WORKSFORME to reflect this.
