kdevelop 3.0.0 segv in kdelibs/kdeui/kxmlguiclient.cpp

[Albert Chin]

I've built kdevelop on Tru64 UNIX 5.1 and am getting a SEGV on
startup. The backtrace:
#10 0x30007214918 in ((KInstance*)0x0)->KInstance::instanceName()
"kinstance.cpp":248
				  ^^^ the problem

#11 0x30006325828 in
((KXMLGUIClient*)0x140223650)->KXMLGUIClient::setXMLFile(_file=& class
QString { ... }, merge='\000', setXMLDoc='\001')

"/opt/TWWfsw/kde32/include/kgenericfactory.tcc":167

The SEGV comes from kdelibs/kdeui/kxmlguiclient.cpp in
KXMLGUIClient::setXMLFile():
  ...
  QString filter = QString::fromLatin1( instance()->instanceName() +
					'/' ) + _file;

How do I debug this? I added some print statements to debug this and
noticed that instance() changed after the call to
KXMLGUIClient::setXMLFile for "kdevmakeview.rc". On Redhat Linux 9, it
changed to a non-NULL value (ditto for IRIX 6.5). However, on Tru64
UNIX, it seems to be NULL.

The failure is from kdevelop 3.0.0.
