Bug#31794: intermittent won't save then crash on close all

[abatters at widomaker.com]

Package: kdevelop
Version: 2.0 (using KDE 2.2.0 )
Severity: normal
Installed from:    RedHat RPMs
Compiler:          gcc 2.96
OS:                Linux
OS/Compiler notes: RedHat 7.1 with custom-compiled 2.4.9 kernel

I am using the editor part of KDevelop for editing console C programs; I compile, run, and debug using a separate console.  I just upgraded from version 1.4 to version 2.0.  With version 2.0, sometimes when I press Ctrl+S to save the file, KDevelop does not actually save it (I can tell by looking at the file in vi and comparing to what the KDevelop window shows).  Pressing Ctrl+S again results in the same thing.  When this happens, the File->Save menu item is greyed out.  Clicking on the Save As menu item does not bring up any dialog box.  I even tried to highlight all of the text and copy it into a different application (to avoid losing my changes), but the copy operation didn't work either (it just pasted something that I had copied a bit earlier).  Selecting File->Close All causes the dialog box to pop up asking if the modified document should be saved; but clicking Yes causes KDevelop to crash.  Here is the backtrace of that crash:

None of these problems show up when I first start KDevelop.  It behaves correctly for a while and then breaks.  I have not yet determined exactly what triggers the problem.

I noticed that bug #31390 involves a crash on Close All, but due to lack of additional details I wasn't sure if this is a duplicate or not.
