I cannot trigger the crash (it happens randomly) As per your instructions, running:
sudo ubuntu-bug /var/crash/_my_crash_report.crash shows the attached pop up window and I get the following message on the terminal: 'Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.' Nothing is actually saved to /var/crash Since I originally reported the crash, Chrome has been updated to 48.0.2564.82 (64-bit) but Xorg is still 1:7.7+7ubuntu4. I don't think I have had any more crashes since then (but I haven't been using Ubuntu/Chrome as much) I originally had the following files in /var/crash: -rw-r----- 1 devbie whoopsie 1712230 Jan 17 15:17 _opt_google_chrome_chrome.1000.crash -rw-r----- 1 devbie whoopsie 613910 Jan 22 22:28 _usr_bin_atril-thumbnailer.1000.crash -rw-rw-r-- 1 devbie whoopsie 0 Jan 22 22:28 _usr_bin_atril-thumbnailer.1000.upload -rw------- 1 whoopsie whoopsie 0 Jan 22 22:28 _usr_bin_atril-thumbnailer.1000.uploaded -rw-r----- 1 devbie whoopsie 7143430 Jan 22 23:38 _usr_bin_mate-panel.1000.crash -rw-r----- 1 root whoopsie 4204066 Jan 18 22:17 _usr_bin_Xorg.0.crash -rw-r--r-- 1 root whoopsie 0 Jan 18 22:17 _usr_bin_Xorg.0.upload -rw------- 1 whoopsie whoopsie 0 Jan 18 22:17 _usr_bin_Xorg.0.uploaded Presumably they relate to the bug and I have saved them for the time being. Would they be useful & should I upload them (how would I do this)?
