XBMC 12.0 Alpha7 - subtitle strange behaviour

Hi all,
I'm writing for help for a subtitle problem.

I'm talking about last Alpha7 XBMC 12.0 update of 27 October (today) installed on updated Linux Ubuntu 12.10 64 bit

Until the last update , everything was OK.

After that, subtitles apparently don't work, I say "apparently" because if I seek forward or rewind the avi file , subtitle appears!
I cannot understand the reason, if someone has an idea please help me.


I tried to clean remove every xbmc related file and recompile everything from latest git but the problem is still there.

xbmc.log doesn't register anything strange, only when I seek it seems to close subtitle stream and reopen it , then subtitles re-appers

any idea?
