--- Comment #12 from Kevin Funk <kevin@kfunk.org> ---
This isn't a duplicate of bug 284536, as that clearly indicates a complete
different backtrace.

It still seems to crash in
KDevelop::CodeHighlightingInstance::typeForDeclaration in current master, as
reported by hippiehunter on #kdevelop.

Backtrace (reduced):
