Version: 3.4.1 (using KDE KDE 3.5.1) Installed from: SuSE RPMs OS: Linux changing project after working in another for a while causes a crash. If I restart and change projects immediately, it works ok. See attached stack.
Please paste the stack in a comment, this makes things easier.

This should be fixed in svn, see commit 665785. I could not reproduce it however, probably the debugger needs to be running when closing the project(or anything else that keeps dispatching events while the projectClosed(..) signal is called). If this does not help, reopen the bug.
The debugger does need to be running to cause the crash. Haven't had chance to test svn yet.
Same conditions (except no debugger), not svn version, different stack: System configuration startup check disabled. Using host libthread_db library "/lib/libthread_db.so.1".

still a problem in kdevelop3-3.4.1-17.1 (not sure what commit this goes up to)
this is still a problem with kdevelop3-3.4.1-70.2: #6 0x00322070 in ?? () #7 0xb710e6cc in QObject::inherits () from /usr/lib/qt3/lib/libqt-mt.so.3 #8 0xb7ec4864 in EditorProxy::setLineNumber () from /opt/kde3/lib/libkdevshell.so.0 #9 0xb7ec4a66 in EditorProxy::setLineNumberDelayed () from /opt/kde3/lib/libkdevshell.so.0
The 2nd stack trace (which is the only one I seem to get with the latest svn version) appears to be failing on this line: kdevelop/src/editorproxy.cpp:73 if (!part || !part->inherits("KTextEditor::Document")) My /opt/kde3/include/kparts/part.h does not appear to define any inherits() method for KParts::Part (kdebase3-devel-3.5.1-69.29), is this added in a later version?
inherits is a QObject method and probably exists since Qt 3.0 at least. Also its crashing inside inherits, so to get more information you probably need to build Qt3 with debug symbols from source so the backtrace includes the line at which it is crashing.
Is it possible EditorProxy:setLineNumber(m_delayedPart) is being called after m_delayedPart has been deleted (ie. a step in closing the project)? I'm not sure if a debug Qt3 would be much help.
It also sometimes crashes like this when 'Close All Others' is selected from an editor tab.
*** Bug 148614 has been marked as a duplicate of this bug. ***
as this is hard to reproduce, nobody's working on the kdevelop3 codebase actively and we're not having this in kdevelop4 I close this as wontfix.
