Mythfrontend on mythtv .22 won't run [solved]

I've updated to mythtv .22, and have run through mythtv-setup successfully.  My backend is running.  When I start mythfrontend, it brings up the blue background screen for a couple minutes, then it ends and returns me to the gnome desktop.

The frontend and backend are on the same machine.

I've looked through logs, but don't see anything that I can relate to this issue.

I pacman -R'd all the plugins before I did my update.

I've rebuilt mythweb in .22 from abs, and that seems to be working fine.

Not sure what other info is relevant, but any ideas are appreciated.

Re: Mythfrontend on mythtv .22 won't run [solved]

This happened to me too, but only on one out of three x86_64 boxes. Mythtv exited with a Floating point exception, no further error messages (not even with maximun verbose)
The problem was solved by removing qt3

I have opened a ticket in the bugtracker (17232) for this, but it is curious that this didn't happen with my other machines, even though they had qt3 installed as well.

Looks like I might have a couple issues, but the floating point error ends it all.

pacman -Q qt tells me I have qt 4.5.3-3 installed

I found some info that this has been caused by failure to remove some old plugins, I have previously removed those with pacman.

On older versions this had to do with a screen resolution issue, so I may play with that after work.

Re: Mythfrontend on mythtv .22 won't run [solved]

It is true that mythtv 0.22 doesn't work with the old plugins, but on my box the frontend did launch after I removed qt3.

Try pacman -Q | grep qt. I bet it will show that both the qt and the qt3 package are installed.
pacman -R qt3 should allow you to launch the frontend. I know this is not a real solution, since some packages still depend on qt3, but at least it will allow you to use mythtv

Re: Mythfrontend on mythtv .22 won't run [solved]

I started removing qt3 as indicated, then realized that pacman -Q|grep myth would tell me if I had missed anything on my plugin removal; I had, mythbrowser was there and I didn't even remember that I had installed it.  By that time I had everything other than qt3 itself removed, but tried and mythfrontend came up.

I'm on i686.

Thanks!
