Re: [Bug: 21.5-b29] assertion failure while typing in minibuffer

Stephen J. Turnbull wrote: It does appear to be correct. I got another crash earlier this evening. This time I had done the following operations: 1. dired an upstream source tree in one frame. 2. dired an edited source tree in a different frame. 3. in the dired window with the edited source, type M-! "diff -ur " 4. select the path in the "upstream" dired buffer 5. move the mouse back to the frame with the edited source, then middle-click in the minibuffer, to the right of the text I had entered so far. Or try to middle-click. I don't remember whether I actually managed to click before the windows went away. So I now have a shiny, new core file that gdb is quite happy to help me analyze.
