[mythtv-users] HELP! mythtv-setup segfaults

Wed Aug 2 18:44:37 UTC 2006

Hi list,

I am having a problem getting mythtv-setup to run. I have been running Myth
for several years now (Gentoo box with usually the latest SVN). This current
problem started when I did an SVN update and mythbackend died at startup due
to a mysql schema change. Well thinking that this might be the time to
update Mysql I went ahead and emerged 4.1.20 from 4.0. Big mistake. I should
have learned by now to check the Gentoo update docs, but no, not this
time... Well this broke a lot of things and took me a lot of work to get
things corrected. Along the way I dusted my mythconverg database, thus the
need to run mythtv-setup. I have set-up the initial database and can connect
with it with Mysql, so that seems fine. When I run mythtv-setup it
immediately segfaults. I have included the first and last few lines of an
strace. I can't see anything that looks wrong but maybe someone can help me
out. BTW this is SVN 10557.

I am going through withdrawal, so hopefully someone has some hints..
