My forum just recently been upgraded to xenforo 1.2rc. When i'm changed thumbnail size and run rebuild i get error all time:
Server Error

Failed to write the attachment thumbnail data.

But then i'm uploading any image into the thread thumbnail processed correctly. I'm tried both php-gd and imagick.

This sounds like a permission issue in one of your older attachments. You should check the ownership/permissions compared to the newer ones (both in the internal_data and data folders).

That said, this is something that we should probably catch and simply log in this rebuild process.
