Comment 20 for bug 423558

I have an assumption why I have this error, some weeks ago I installed Pro/Engineer on my computer.
It is a cad-system from PTC.

Normally you need this packages:
csh
libmotif3
libstdc++5
build-essential
libgtk1.2
nfs-common

libstdc++5 and libgtk1.2 are newer in Karmic, so I installed the packages by hand.
Please check this here:
http://wiki.ubuntuusers.de/ProEngineer

http://packages.ubuntu.com/jaunty/libstdc++5
http://packages.ubuntu.com/jaunty/libglib1.2ldbl
http://packages.ubuntu.com/jaunty/libgtk1.2-common
http://packages.ubuntu.com/jaunty/libgtk1.2

May be if I remove these packages my nautilus will run, but what will be happend with Pro/Engineer? I need this cad-system for work.
