To provide some context, when this crash can happen: It can happen, after attempting to start a remote desktop session, when the screen is locked. In such case, g-s directly refuses the start request and therefore the lifetime of the rdpgfx thread in FreeRDP is very short.
The journal message for this looks like this: `Failed to start remote desktop session: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Session creation inhibited` Now, the error here is, that FreeRDP does not correctly wait for the rdpgfx thread to be created and this can lead to in this situation, that the rdpgfx thread is not teared down, when stopping the session, which can can lead to segfaults, like in this report or to memory corruption. Personally, I was not able to reproduce the error. However, with the help of the journal entries I was able to find this cause. https://github.com/FreeRDP/FreeRDP/pull/7836 takes care of the problem. Sessions, that are not locked, should not be affected by this issue. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to freerdp2 in Ubuntu. https://bugs.launchpad.net/bugs/1970994 Title: /usr/libexec/gnome-remote-desktop- daemon:11:setChannelError:rdpgfx_server_thread_func:thread_launcher:start_thread:clone3 Status in freerdp2 package in Ubuntu: Triaged Status in gnome-remote-desktop package in Ubuntu: Triaged Status in freerdp2 source package in Jammy: Triaged Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding gnome-remote-desktop.
