Oops sorry about that - thought I'd reinstalled the debug symbols before the last backtrace, but clearly not. Please find new backtrace, attached.
I'm keeping this current installation with a view to helping with diagnosis of this issue. As far as I'm concerned, that's fine for the moment (I very rarely use the GUI to manage software packages). But, being that it's quite possible that a fresh install would solve the issue (reinstalling and missing/corrupt packages, for example), then let me know and I'll just wipe and reload at some point. Essentially, I'm not bothered about this issue being investigated/solved for my own purposes, but if you feel it may be useful to pursue this possible bug in terms of the wider community, then I'm more than happy to keep the current install as-is for the moment, with a view to assisting with that process. As regards the snapping of my own application, thanks for the heads-up about the forum. I did raise a question there several weeks ago, but in the end it just wasn't worth the time/hassle to sort it out. I'm sure the issues I were having were just the result of me somehow messing it up, and the app in question was just a demo thing that I doubt anyone would really be interested in. It was just a preliminary experimentation using snap really (a very exciting distribution method, that I look forward to playing with again soon!). ** Attachment added: "backtrace.gnome-software.19-oct-2017.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1720442/+attachment/4976549/+files/gdb-gnome-software.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1720442 Title: Software (gnome-software) crashes after several seconds.
