*facepalm*

Despite the fact that pre/post scriptlets are *rarely* needed in the first place, these of course have to cope w/ broken installations (otherwise defeats the whole idea of package management).

You can remove the packages manually by calling rpm directly - w/ '--noscripts' flag.

(might leave some garbage that the scripts supposed to clean up)

@NI: is it really so hard getting some experienced devops engineers for the linux packaging ? Last time I had a call w/ NI folks, they told they only have 1..2 people (IIRC even just part time) for the Linux stuff. Obviously this can't work. 

Folks, if you need help, just call me. I can even arrange a larger team of experts

if needed.
