>Thanks for the patch! I applied it and it fixes the issue - no more segfault. It is hard to believe that this problem was actually found in real life. Was it? I.e., I find it hard to believe that the patch actually helps anyone's workflow to proceed. But maybe I'm wrong... I was also a bit amazed at how extensive the patch is - seems to require quite a few changes to quite a few files. None of this should be interpreted as in any way implying that it isn't an interesting read and/or a good patch. ================================================================================= Please do not send me replies to my posts on the list.
