-- Information about the crash:
- What I was doing when the application crashed:
KDevelop crashes while going on symbol information/go to definition, I can reproduce only sometimes but not in a stable, meaningful way, though it sometimes crashes after KDevelop has been opened for a while.

The reporter is unsure if this crash is reproducible.

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

The backtrace is very similar to the one in Bug 453684 you have reported earlier. Two likely causes:
1. Something related to accessibility is broken on your system.
2. A KTextEditor bug, possibly regression, related to accessibility.

Makes sense that Qt could be also the problem here, I could try to see if some issues/bugs is known related to accessibility in Qt, how ever I don't seem to crash with others applications that uses these classes. Though, I could try to see what's going on with more debugging and looking online, see if there's people having these accessibility issues.

This crash is common in KDevelop: https://bugs.kde.org/buglist.cgi?quicksearch=QAccessible%3A%3AupdateAccessibility&list_id=2061194. But Dolphin seems to be affected too.
