It seems the migration of the wiki history towards aaj doesn't properly deal with gziped history.

I think its related to string encoding in MySQL vs. in the serialized yaml that is used in aaj. But I might be wrong here. I still need to build a test setup for that as I couldn't reproduce this yet.

The issues was observed by at least Z-95 and Skaag (who uses MySQL) on IRC.

Correct deflation of gzipped wiki text. #523


Updated by Felix Schäfer at 2011-07-28 10:05 am

Not a problem of MySQL, but an oversight while updating the wiki code for aaj. Here's the fix:
