A problem with syncing checksums

[Operator]

Hello everyone! After upgrade on 80.5 my friend has some problems with multiplayer. Game and lobby were installed from spring repo on Ubuntu 9.04 x86. He is not registered on this forum, so, I'll speak from his face. Here's a problem:
"I encountered a strange bug in spring 80.5 and 80.5.1 - in singleplayer everything is ok, but if try playing multi - lobby says that my mod's checksum does not match with hoster's, even though I've checked it myself and it's ok."
Problem affects both 80.5 and 80.5.1 releases of Spring and 0.28 and 0.29 Springlobby. If it will be useful, unitsync.log placed here http://pastebin.com/m44df6e61

He has copied his base contents to his home directory (springcontent.sdz in $HOME/.spring/base, basically all content of $HOME/.spring/base). Tell him to delete the directory and never do this again.

Thanks for help! Doing so made a good result - game works good now.
