Comment 1 José Matos 2008-05-24 07:16:43 UTC

Where does qt-4.4.0-4.fc9.x86_64 comes from? I don't see it on koji.

On the other hand what I see on koji is lyx-1.5.5.

lyx-1.5.4 was released before qt-4.4.0, lyx-1.5.5 was released after and it
fixes the compatibility problems with qt-4.4.

Comment 2 Ben Boeckel 2008-05-24 14:27:12 UTC

Rex had built qt-4.4.0 and I got it from him. Using it with qt-4.3.4 does not
crash (reported by someone else on IRC). I'll try the 1.5.5 build and report back.

Comment 3 Rex Dieter 2008-05-24 15:22:50 UTC

Right, so this isn't strictly anyone with stock fedora would see atm, but...
I've build lyx-1.5.5, I just hadn't gotten round-tuit at issueing an update.

JosÃ, can you issue the update?  (Else, I'll get it it eventually).

Comment 4 José Matos 2008-05-29 15:48:05 UTC

I have been both swamped by work and today I was bitten by this problem so I
have issued an update for F[7-9].:-)
I requested a push to the updates since the reactions to this release have been
very good.

Comment 5 Rex Dieter 2008-05-29 16:31:20 UTC

make sure to reference this bug in the update request.

Comment 6 José Matos 2008-05-29 16:45:56 UTC

Done.

Comment 7 Rex Dieter 2008-05-29 16:55:19 UTC

thx, but straight to stable, bypassing updates-testing, are you that brave? :)

Comment 8 José Matos 2008-05-29 17:07:10 UTC

I had feedback from users of F9 issuing a +1 for this release.

Using thus this "+3 karma" rule I have bypassed testing. :-)
