-- Information about the crash:
- What I was doing when the application crashed:
switch there and back again git branches, and some files disappear and than arrive again.
close kdevelop to reload all files and not answering many times "File changed ... Reload it"
kdevelop crashes

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