Changes between Initial Version and Version 1 of Ticket #229, comment 12

initial	v1
9	9	* with 64-bit Linux builds the crash does not occur with any drivers (I've tested: radeon, nouveau, intel) - structure packing issue, memory address layout more likely?
10	10	* with 32-bit Linux builds the crash does occur (all drivers? all libav versions?)
11		* with a fixed quality the crash does not occur (so: encoder re-init seems to trigger the bug)
	11	* with a fixed quality the crash does not occur (so: decoder re-init seems to trigger the bug)
12	12	* with the [http://xpra.org/trac/attachment/ticket/229/fake-gl-yuvdecode.patch fake-gl-yuvdecode] patch the crash does not occur (so re-init alone is not sufficient, we also have to call decode on a re-initted encoder to trigger the bug)
13	13	* with the [http://xpra.org/trac/attachment/ticket/229/gl-decode-in-UI-thread.patch gl-decode-in-UI-thread] patch the crash does not occur (even though the patch is wrong and can trigger races since the video_decoder is used without locking)
