After further investigation, it looks like a charset issue. I discovered 
that under some (for me unknown) circumstances, rows saved in cache_hash 
with field ident set to TS TEMPLATE is not unserializeable. I found the 
place where unserialize() chokes, and it reads: s:6:"müsli". Apparently 
PHP interprets the ü character as two characters when the typoscript 
setup is serialized. But I have no idea why, and what triggers this to 
happen. It seems to happen randomly, maybe each 20:th page load.

The database is in utf-8, and forceCharset is set to utf-8. I have also 
set [SYS][setDBinit] = SET NAMES utf8 SET CHARACTER SET utf8

Does anyone have any idea what could be causing this?
