When launched form the Applications menu or the Message menu I get an apport crash.

I'm using the latest Lucid (Linux duncan-desktop 2.6.32-18-generic #27-Ubuntu SMP Fri Mar 26 21:13:44 UTC 2010 x86_64 GNU/Linux) with the latest lucid build of gwibber (2.29.94-0ubuntu1, not the nightly ppa).

I've now switched to the nightlies (currently 2.31.1~bzr706-0ubuntu1~daily1) and I'm still having this problem. I get exactly the same console output as in #4 and gwibber still won't start.

Hmmm... figured it out, duh. Gwibber won't start with a non-integer default application font size, like the error says. Mine was intentionally set to 10.5 point in System -> Preferences -> Fonts -> Application Font. sbas's is set to '8.599609375' (huh? Where did you get that value from?). If I set mine to '10', Gwibber starts ok - sbas, could you try changing yours to '9' and seeing if that fixes it for you too?

I'm going to re-title this bug to reflect the actual cause.

[Duncan Lock (dunc)]

This maybe a duplicate of this bug?:

[sbas (sbas)]

yes, duncan, gwibber works setting application font size to an integer. i changed the value from 8.6 to 8 and, yes, it works.
8.599609375 is 8.6 :)

[Omer Akram (om26er)]

Thanks for taking time to report this bug. This particular bug has already been reported but feel free to report any other bugs you may find

[Omer Akram (om26er)]

oops wrong bug.

[Inash Zubair (inash)]

This is definitely a duplicate of #425929. I was hit with the same problem as sbas as I keep my application font size same as sbas's. I've proposed a possible fix for it and have proposed for merging. It's just a one liner. If you open the file /usr/lib/python2.6/dist-packages/gwibber/gwui.py and search for:

self.web_settings.set_property("default-font-size", int(font_size))

which comes under WebUi.render method and change it to:

self.web_settings.set_property("default-font-size", int(float(font_size)))

will fix the problem for you.

[sbas (sbas)]

thanks Inash, it worked :)

[Kamus (kamus)]

There is a lot of people affected and I have checked the latest stable version of gwibber and exact line that belongs to gwui.py has not been changed yet.

[Inash Zubair (inash)]

Hopefully the change will be merged soon.

[Ashley Yakeley (ashley-semantic)]

It's specifically "Application Font". I have them all set non-integral, but it works when I set that one from 8.25 to 8.

[Omer Akram (om26er)]

Please read comment#11 it should fix the problem

[sbas (sbas)]

thanks Omer, as i said in comment 12, it fixes the problem.

[Omer Akram (om26er)]

Ken, can you please review this branch... its a one line fixer.

[Martin Pool (mbp)]

tested branch ready for merge here:

[Caracuri (caracuri)]

can be fix converting self.web_settings.set_property("default-font-size", int(font_size)) into eval?
