 Thanks for this new version!
 The update went fine (although i had to manually trigger it and the
 automatic updater found none, the log shows no time though).

 What happened:
 - clicked on the X of a tab which was busy
 - TB disappeared

 The js error is probably unrelated since the log is full of it:
 {{{
