Bug Description

Binary package hint: libcairo2

Upgrading to libcairo2_1.4.10-1ubuntu4.2 solved the floating point exception problem many people had with libcairo2_1.4.10-1ubuntu4.1. However now it does not render all text on widgets (widgets seem to be of right size though). I have just upgraded to libcairo2_1.4.10-1ubuntu4.2, started pidgin and had almost all menus empty. Parts of text were missing on other widgets as well. Had to downgrade to libcairo2_1.4.10-1ubuntu4 again.

Using Serene raster fonts from xfonts-bolkhov-75dpi package. amd64 arch.

I also have the same problem. In my case some Chinese fonts could not be rendered in pidgin if there are whitespace characters between two Chinese words.

Could you try if the gutsy-proposed version fix your issue?

The proposed fix is related to bug 116236, which actually predates the security update. (?!)

Thanks to Jamie's help with font wrangling, this has been reproduced. Additional upstream fixes have been tested now. This was actually a pre-existing problem (bug 116236) that was uncovered due to the recent memory allocation fixes. The updated packages are making their way through the security build queue now.
