Comment:

 Replying to [comment:3 Arnaud]:
 > In any case the video in available (see comment 1) so you should be able
 to easily reproduce the problem.

 I disagree and please understand that while I am thankful that you opened
 this ticket, I have to add that I find it rude to use open source software
 without providing the local patches to the developers (no matter if the
 patches will be used or not).

 Anyway: This could be considered a regression since
 ecf442a58b09bdb1dc1d2c3904b82ac5f79b2878 related to tickets #1294 and
 #1666, could also be considered a duplicate of ticket #3499.
