-- Information about the crash:
KDEvelop chashed when I rename a file of the current project out of IDE. I renamed (with svn mv command) file certificado.php to svg.php in a terminal window and when I tried to open svg.php file, the crash happened :-)

The crash can be reproduced some of the time.

 -- Backtrace:
