Apologies, my last mail didn't have all the facts. In paragraph 3 of the original bug report, I am referring to line numbers in the file Xi/exevents.c.
Also, this bug started happening when I updated my xserver-xorg* packages from 2:1.14.4-1 to 2:1.15.0-2. It seems likely that the update from 1.14 to 1.15 introduced the breakage, although I haven't tested the intermediate package versions (mostly because I can't reliably trigger the bug), and a debdiff between those two versions doesn't show any obviously related changes. -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
