GTG crash in startup

[Firas Ghanim]

After updating liblarch to latest version (0.2.5.r135~precise1) today, gtg wouldn't start. It crashes immediately after start without displaying the tasks list window.

GTG: 0.2.9.r1234~precise1
Ubuntu: 12.04
Gnome: 3.4.2
Kernel: 3.2.0-32

gtg -d:

I am sorry. There is a major change in liblarch and the needed code in GTG is not merged yet. Please, downgrade liblarch. Sorry for inconvenience.

I got hit by this one today, too. It would be a good idea to get the new liblarch removed from the gtg PPA.

[Matt Lavin (matt-lavin)]

I hit this today and it look me some time to figure out the right version of larch to revert to. The latest version that worked for me was 0.2.5.r134

[sergio (serge-simon)]

Same problem for me.
Is liblarch used by any other programs (in order to know if i can downgrade without any risks) ?
(moreover, if liblarch is specific to gtg, then it's weird to have this dependency problem)

[sergio (serge-simon)]

Ok, was unaware that liblarch is probably anyway only used by GTG.
So it's quite weird to have such a broken dependency in the PPA !

As a side note, after a few tries, the easiest thing to do right now in order to have GTG working again at this time :
- grab the sourcecode of liblarch from this commit (newer ones doesn't work) : https://github.com/liblarch/liblarch/tree/d4df5ab970745dc1372fcdeec5648c9232c89cb1
- uncompress it in /usr/share/liblarch/
- run GTG with something like "cd /usr/share/gtg/ ; ./gtg -l"
