Bug#43912: Crash when adding many existing files to a project

Fri Jun 14 10:34:02 UTC 2002

Package: kdevelop
Version: 2.1.1 (using KDE 2.2.2 )
Severity: normal
Installed from:    Debian testing/unstable Packages
Compiler:          Not Specified
OS:                Linux
OS/Compiler notes: Not Specified

Some uses have reported a crash of KDevelop when adding many existing files to a project.

Here is how to reproduce the bug.
- Open any existing project
- Menu: Project/Add existing files
- click on the small "Open File Dialog" icon next to the edit
"Sourcefile(s)" (btw. you can't enter any text in the edit, so why is it
enabled and not disabled?)
- resize the window (manually) to fit the whole screen
- whether preview is on or of does not matter
- change to /usr/doc (if you have a fully installed debian with many
packages) or /dev (you seem to have to select about 300 items within /dev.)
- begin to select the directories by dragging a frame from topleft corner
slowly to bottom right.
- notice the strange select-behaviour of the dialog. Sometimes it flashes
all dirs in the same row your mouse is currently over for about half a
second. (This happens with /usr/doc on me, not within /dev...)
- continue. If you have selected about 100 Items, kdevelop will crash
without any comment.

Here is a backtrace from the crash.
