Unfortunately, I've crashed eric again with current snapshots as available 
on: 

http://download.opensuse.org/repositories/home:/frispete:/branches:/KDE:/KDE4:/Factory:/Desktop/

To be exact, it's sip-4.9.1-snapshot-20091014.tar.gz + yesterdays fix,
PyQt-x11-gpl-4.6.1-snapshot-20091014.tar.gz, eric 4.3.8, and pysvn 1.7.0.
The whole suite is build against Qt-4.5.3 now. 

Again, I've committed a newly added directory (8 binary files with a total of 
6kb) in a small project. On the commit confirmation dialog, I hit close 
immediately, when it turned enabled, which triggers the crash. This is pretty
reliably reproducible that way.

On the plus side, I can confirm, that the new approach to fix 
sipForceConvertToType for mapped types is still functional and the latest 
monkey patch test case from Adeodato appears to behave as before sip-4.9.
