Bug#39105: kdevelop crashes when C++ code completion popup closes

[d.kamenopoulos at mail.ntua.gr]

Package: kdevelop
Version: KDE 2.9.2 CVS/CVSup/Snapshot
Severity: normal
Installed from:    Compiled sources
Compiler:          Not Specified
OS:                Not Specified
OS/Compiler notes: Not Specified

Code completion works fine for C++ (latest CVS) apart from the fact that every time the popup with suggested completions closes, KDevelop crashes. It doesn't matter how the popup is closed. I can click on a possible completion, press space or even type the whole completion myself. The result is always the same. Here is a backtrace:
