           Summary: crash on clicking docbook compilation errors in messages
                    window
           Product: kdevelop
           Version: 3.0.0b1
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: klee at cs.washington.edu

Version:           3.0.0b1 (using KDE 3.1.93 (CVS >= 20031111), yes)
Compiler:          gcc version 3.2
OS:          Linux (i686) release 2.4.21-1up.1

To trigger a reproducible crash:

1. I open a KDevelop project and close *all* my document windows, so that no files are open and the main workspace is empty.  I am using the IDEAL MDI mode.

2. I compile my project's docs, and I get errors in a docbook file.

3. I click on the error message.  This makes the docbook file open in the main workspace.

4. I close this file, so that the workspace is again empty.    This also makes the messages window disappear.

5. I reopen the messages window and click on the same error message (or, actually, any docbook error message).  This should open a new document window with the same file.  Instead, it crashes.

Oddly enough, this crash does not happen when I introduce a compilation error into a C++ file in the very same project, and repeat the above steps.  It does happen whenever I click on a docbook error message, close the window, and click on another docbook error message twice in a row.

Backtrace follows.  I am using latest qt-copy and kde* out of HEAD from a few days ago.
