@dbungert: While the patch that simply copies the list is a possible way of doing things, a very experienced user on the Arch Linux forums had concerns about doing things that way, see https://bbs.archlinux.org/viewtopic.php?pid=2090570#p2090570 "But creating a copy of the list is inefficient and only glosses over the actual problem (and probably will cause X11 errors and/or behavioral differences - maybe maintain them b/c of the status quo ante)"
In the two-item case, as long as the rest of Openbox code keeps the list consistent after removing *and adding* an item (because keep in mind the code doesn't just remove stuff, it also adds stuff), everything should be fine. itPrev->next should point to a valid item unless the underlying list has become corrupted. In the one item case, the first iteration through the loop works, and with only one item, there will only be one iteration through the loop, so presumably the crash won't happen unless the one item case triggers a crash in some other way. I'll test both and report back what happens. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/2011751 Title: openbox crashed with SIGABRT Status in glib2.0 package in Ubuntu: Invalid Status in openbox package in Ubuntu: Confirmed Bug description: Lubuntu lunar (primary box) on - dell [optiplex] 7050 (i5-6500, 16gb, intel hd530/i915) I experienced a crash yesterday (openbox) but tend to ignore the first crashes... Whilst using the machine again today a crash occurred. This is my primary box, so my setup is pretty consistent - featherpad (restored session) - hexchat (irc) - qterminal (only single tab today; usually many) - firefox (snap, most sites excluding google related) - chromium (snap, used for anything google related) - telegram (snap) - element I was using chromium full screen (trying to read my gmail inbox) when borders around windows disappeared & I lost the capacity to switch between windows; mouse would move, but keyboard appeared mostly dead (it wasn't, more I think windows weren't responding, inc. clicks with mouse though that's likely inconsistent; I could work out how to describe it yesterday, but todays is almost identical). I switched to text terminal (ctrl+alt+f4) & explored; returned to GUI and used - ctrl+alt+t to open new terminal - openbox & session returned to what I expect... ** expected outcome Openbox doesn't crash ** actual outcome all windows lost borders, and i lost ability to switch between windows I appeared to have minimal control (not true, more a fraction of what I expect) ** How to get crash For me, - I used chromium (browser) - make chromium full screen (ie. F11) - click on something & right-click to open in new window OPENBOX CRASH.
