same error in python 2.6 though

Same problem on my system. Freshly installed F11 and at the first system update get this error. The errors are exactly the same however I seem to have got a later version of python, so attaching a screenshot - so you have the required info.

I noticed my system time and date had changed to September 1994 and a time in the evening. I recently updated my system from FC10 to FC11 and then ran the yum update command on 6-25-09 and now I get the internal system error that says, "more than one preupgrade package installed".

An internal system error keeps re-occurring.

Sounds like there is a lot going on (and wrong) on this system.

Have you been experiencing any other random events? Segfaults?

I only get the internal system error that says, "more than one preupgrade package installed" randomly appearing since the last couple updates -- no other problems. This is a dual-boot system (WinXP/FC Linux), with multiple Fedora Core Linux OS's (FC8, FC10, & FC11).

Got this repeating "Internal System Error" message. Below are the details.

This bug is another issue, it is because the current rpm-warm-cache don't play nice with PK, if you don't need it then remove it

yum remove yum-plugin-rpm-warm-cache

the issue is fixed in upstream yum-utils and in rawhide, but can't be released in F10.

I have done your suggestion as below.

yum remove yum-plugin-rpm-warm-cache

Seems to be working fine now. Error message not popping as of now.
Thanks Tim.
