fvwm2 crashes frequently after upgrade to Ubuntu 13.04

[Peter Selinger]

I just upgraded to Ubuntu 13.04. Now fvwm2 crashes frequently (i.e., every few minutes) and drops me back to the login prompt, typically while I am working with Firefox.

I have captured fvwm2's standard error stream as follows:

[fvwm][FlocaleGetFontSet]: (-adobe-helvetica-bold-r-*-*-12-*-*-*-*-*-*-*) Missing font charsets:
ISO8859-3, ISO8859-4, ISO8859-5, KOI8-R, ISO8859-7, ISO8859-9, ISO8859-13, ISO8859-14, JISX0208.1983-0, KSC5601.1987-0, GB2312.1980-0, JISX0201.1976-0
[fvwm][convert_charsets]: WARNING -
        Invalid byte sequence during conversion from UTF-8 to ISO-8859-1
[xcb] Unknown sequence number while appending request
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
fvwm2: ../../src/xcb_io.c:161: append_pending_request: Assertion `!xcb_xlib_unknown_seq_number' failed.
Aborted (core dumped)
fvwm2 terminated with exit code 134

I have not been able to find the core file that was allegedly dumped. Please let me know if there is other useful information I should post.

Thanks, -- Peter

This looks like the same issue as the one I just reported at https://bugs.launchpad.net/ubuntu/+source/fvwm/+bug/1289535

I can attest that this happens even in my copy of compiled fvwm.

Status changed to 'Confirmed' because the bug affects multiple users.
