Often, but not always, an error occurs saying that a method of non-object has been called, in ObjectCache.php and in Title.php. An investigation shows that it is because of $wgContLang being null. At the same time, although the file caching is on, wiki almost does not respond. This was not the case before upgrading from 1.4.5 to 1.4.9. I am not sure about operating system and platform; we are running at SourceForge. Thanks a lot.
I think, this is related to the problem which I reported in http://bugzilla.wikimedia.org/show_bug.cgi?id=1805 "new User() objects see undefined $wgContLang due to early call of loadfromsession() in Setup.php" The problem can be solved by a slight delay (move) of a few lines of codes, see the patch in 1805. (EnotifWiki has this problem solved.)
I have downgraded the severity of this bug. Without any action on my side, our wiki is working fine again. Also, the file cache seems to take effect now. My guess is that the bug appears under rare circumstances, which is why it has not been detected and removed before in the first place.
Reopen if this recurs in current trunk; suspect it was fixed ages ago.
