The crashes that failed to retrace all seem to have the following stacktrace: ?? () g_io_channel_shutdown () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 ?? () from /usr/lib/x86_64-linux-gnu/libpackagekit-glib2.so.18 g_main_context_dispatch () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 ?? () from /lib/x86_64-linux-gnu/libglib-2.0.so.0
Which suggests they are a bug in PackageKit. A quick look at the PackageKit source shows this is done in a callback that may still be running after an object has been unreferenced. So I don't think they're related to the Snap changes. The crash with the backtrace seems to be related to the network monitor changing state (network disconnected/connected?). So I don't think it's related to the Snap plugin. -- 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/1716633 Title: Installed, popular and featured snaps are loaded in parallel threads can crash Status in gnome-software package in Ubuntu: Fix Released Status in gnome-software source package in Xenial: Triaged Status in gnome-software source package in Zesty: Triaged Status in gnome-software source package in Artful: Fix Committed Status in gnome-software source package in Bionic: Fix Released Bug description: [Impact] GNOME Software has a cache that can be accessed by multiple threads. This can cause GNOME Software to crash. This seems to have been caused by adding support for featured snaps (bug 1663097) as the popular, featured and installed snaps are all requested on different threads. [Test Case] Since this is a random crash there's not a good test case. Could be checked by looking at errors.ubuntu.com crash reports or repeated restarts of GNOME Software to see if it crashes on startup. [Regression Potential] Solution is to add a lock around this cache. Some risk of breaking related code.
