Bug#41813: Crash after files become wrongly labelled

[djarvie at lineone.net]

Package: kdevelop
Version: KDE 3.0.0 
Severity: normal
Installed from:    SuSE RPMs
Compiler:          gcc 2.95.3
OS:                Linux
OS/Compiler notes: kdelibs, kdebase compiled from source (with objprelink)

I had a number of files open in KDevelop. I opened another (say, x.h), and then switched back to one of the previously opened ones (say, y.cpp). Things were fine for a few seconds, and then I was unexpectedly switched back to x.h, without doing anything to prompt this. When I reselected y.cpp, its contents were displayed in the editor, but the title bar still said "x.h". I tried selecting other files, and the title bar still said "x.h", while displaying the correct contents. Then, I started to close KDevelop down, and it displayed a prompt about saving y.cpp. I clicked cancel and continued to edit. It then crashed (backtrace below).

Note that my KDevelop is the SuSE 7.2 RPM, while my QT, kdelibs and kdebase are compiled from KDE 3.0 source using objprelink. I have had no stability problems with this build.
