Description Krzysztof Halasa 2016-03-10 12:43:47 UTC

Description of problem:
Emacs crashes when the user uses "File" -> "Visit New File", types initial letter(s) of the file name, and selects existing file name from the list. Interestingly, it doesn't happen with "File" -> "Open File".

Version-Release number of selected component (if applicable):
emacs-24.5-7.fc23.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. start emacs (with X11 - e.g. "emacs -Q")
2. select from menu: "File" -> "Visit New File"
3. type a letter (used to filter displayed file names)
4. select the file with mouse

Actual results:
Emacs crashes with:
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

Comment 1 Jan Synacek 2016-03-15 08:20:42 UTC

I can't reproduce this. Could you please try with Emacs 25?

Comment 2 Krzysztof Halasa 2016-03-21 11:15:24 UTC

The problem still exists with Emacs 25. However, I made another dnf update, and the problem went away (with both Emacs 25 and the mainline 24.5). It is gtk which makes the difference: gtk3-3.18.7-2.fc23.x86_64 crashes Emacs, and the new gtk3-3.18.9-1.fc23.x86_64 does not.

Thanks.
