After upgrading from beta2 to rc1 Qt Creator started to crash pretty consistently upon trying to go to the error location. The sequence is as follows:

1. Build a project with some compiler warnings and an error in it.
2. Once the build (unsuccessfully) finishes, Qt Creator opens the Issues pane.
3. Click the warnings icon on the the Issues pane toolbar to remove warnings from the list.
4. Double-click on an error in the Issues pane.
5. Qt Creator crashes.

Unfortunately, no crash dump or stacktrace. Qt Creator beta2 didn't crash. It seems that step 3 is crucial - if I just scroll down to the error without switching warnings off, the crash doesn't reproduce.
