Eh... if my analysis is correct the bug will be dependent on some non-deterministic things including timing and layout of blocks of the file which the filesystem touchs during suspend/resume. I'm fairly sure the problem is still there. Oh well, it seems I'll have to construct a synthetic case to test it. Anyways, please let me know if you encounter the problem again. I'll keep you in loop with further patches.
