Hello Florian,

you didn't mention the OS you are running CSS upon. But if you (try to) run Eclipse 3.x (or a CSS based on it) on a more or less up-to-date linux distribution
there are some known bugs related to GTK:

* KDE Bug 327441 - Using oxygen-gtk2 causes eclipse/swt to crash (https://bugs.kde.org/show_bug.cgi?id=327441)  --> our workaround is to use another theme by setting GTK2_RC_FILES=/usr/share/themes/Raleigh/gtk-2.0/gtkrc
* Eclipse Bug 404776 causes a crash when opening Help (https://bugs.eclipse.org/bugs/show_bug.cgi?id=404776) --> our workaround is to open it in an external browser instead, i.e. setting the VM param -Dorg.eclipse.swt.browser.DefaultType=mozilla
* displaying issues when using GTK3 --> our workaround is to use GTK2 instead by setting SWT_GTK3=0

I can add one to this list: https://bugs.eclipse.org/bugs/show_bug.cgi?id=464554

I actually spent some time looking into the horrible mess that lives at the bottom of eclipse/SWT.  From what I can tell, in some situations, GTK pointers are being mistakenly passed to libcairo functions, which of course leads to a crash.  The wonders of JNI...

cs-studio-nsls2 comes with some defaults which avoid this, by using gtk2 w/o cairo.  Of course gtk2 will eventually go away, so not a permanent solution.

An excerpt from cs-studio.ini

--launcher.GTK_version
2
-vmargs
...
-Dorg.eclipse.swt.internal.gtk.cairoGraphics=false
-Dorg.eclipse.swt.internal.gtk.useCairo=false

You might also get some improvement by recompiling the eclipse-gtk C glue code against the headers provided by your linux distribution.  Though be warned that this is an errand only for those who can tolerate significant amounts of frustration.
