plymouthd crashed with SIGSEGV in ply_event_loop_process_pending_events()

[Anthony Harrington]

This started happening today after logging in. Nothing peculiar visually on boot up or login - i'm just warned that an error occurred with plymouthd.

I think this is related to the fact that i removed plymouth-label; plymouth-theme-ubuntu-logo and plymouth-theme-ubuntu-text yesterday evening, to see if it had any effect on bootup time - if it does, it's not all that noticeable. But it's one less thing to load at startup and i read that only the plymouth package itself is essential.

If it's not related to these above changes i made yesterday, it'll be something to do with the updates pushed yesterday i.e.

libplymouth2 (0.8.2-2ubuntu25) to 0.8.2-2ubuntu26
plymouth (0.8.2-2ubuntu25) to 0.8.2-2ubuntu26
plymouth-label (0.8.2-2ubuntu25) to 0.8.2-2ubuntu26
plymouth-theme-ubuntu-logo (0.8.2-2ubuntu25) to 0.8.2-2ubuntu26
plymouth-theme-ubuntu-text (0.8.2-2ubuntu25) to 0.8.2-2ubuntu26
