bgardnerkrytarik: Morning!  Okay, upgrade complete, that was interesting.  Now running Ubuntu 15.10, but the error has not changed.  /var/log/apport.log has lots of entries for /usr/lib/menu-cached, plus more pouring in about every 2-3 seconds.13:55
bgardnerSorry, typo: correct path is /usr/lib/menu-cache/menu-cached.  I'm going to dig around and see if I can find the root cause.14:05
krytarikbgardner: Hi.  Can you pastebin some of those please?14:08
bgardnerkrytarik: You bet.  Give me a minute to gather them.14:09
krytarikAlso, I suspect some corrupt .desktop or menu file in either your home directory or system-wide.14:09
bgardnerkrytarik: I believe you, but it's a new install so no immediate idea where to look.14:10
bgardnerkrytarik: http://pastebin.com/V3WjqGGB14:11
krytarikShould have waited for the paste before saying that, I guess. :P14:13
bgardnerkrytarik: Still seems likely, though.  I just don't know where to start looking or what I'd be looking for.14:14
bgardnerkrytarik: New info:  "$ /usr/lib/menu-cache/menu-cache-gen -v -i /etc/xdg/lubuntu/menus/lxde-applications.menu -o /dev/null" -> Segmentation fault (core dumped)14:31
bgardnerI got the command from the README on github for menu-cache14:31
bgardner /etc/xdg/lubuntu/menus/lxde-applications.menu is perfectly readable and seems correct to me.14:33
krytarikbgardner: Reg. "Clicking 'Run' crashes the lxpanel", does it still do that after the upgrade? - LP bug 104402914:40

bgardnerkrytarik: X is so busy popping Apport windows that it's entirely unusable.  I'm afraid I can't answer that.14:41
bgardnerAlso, I've confirmed that /usr/lib/menu-cache/menu-cache-gen dumps core when run on any *.menu file.  Not sure if that helps or not.14:41
krytarikbgardner: Then how about actually using one of those to report it as a bug, as I didn't come across any already reported ones like that yet, and then just disabling Apport for now? - http://askubuntu.com/questions/93457/how-do-i-enable-or-disable-apport14:49
bgardnerWill do14:50
bgardnerkrytarik: Okay, with apport shut off I have been able to get my desktop back and test, and Run does still crash the panel.  Let me go read that bug report and see if it helps.  Thanks!15:06
krytarikSure.15:07
bgardnerkrytarik: I did some debugging with gdb and it turns out this bug (https://bugs.launchpad.net/ubuntu/+source/menu-cache/+bug/1437966) is a more exact fit for my error message, except that the source library is an ARM library, of course.15:23
