           Summary: kdevelop (IDEAl mode) crashes by (multiple) rmb clicks
                    on tab (crash, bt?)
           Product: kdevelop
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel kdevelop org
        ReportedBy: marco.krohn gmx de


Version:           3.0.90-CVS (using KDE 3.2.90 (CVS >= 20040117), compiled sources)
Compiler:          gcc version 3.3.3 20040125 (prerelease) (Debian)
OS:          Linux (i686) release 2.4.23-1-k7

The following is a strange one, but crashes kdevelop reproducable for me:

1. load any project (I have tested php, c++) with at least two tabs (using IDEAl mode)
2. click multiple times with the right mouse button on one of the tabs (left or right tab, active or non-active is not important). Do that fast and slowly move the mouse around (still over the tab) and move it over the close-button

KDevelop than crashes for me with the following bt:

I am afraid it's not too useful--perhaps a Qt bug? Qt unfortunately is compiled without debug info.

Testing the same thing with konqueror does not crash konqueror. While trying to reproduce that I sometimes only had to click 2-3 times, sometimes up to 20 times, but every time kdevelop crashed. Also I am quite sure that I have seen for a very short time a context menue showing up exactly when the crash happened (looking like one of these you get in konqueror). Strange...
