The notifications emitted by the mail-notification applet look really ugly in the Gnome 3.2 desktop due to the use of unsupported '<span>' tags. Quoting https://bugs.launchpad.net/mail-notification/+bug/799852 : The "Desktop Notification Specification" (http://www.galago-project.org/specs/notification/0.9/x161.html) allows only a very limited set of markup. mail-notification emits '<span weight="bold">' tags (which can be expressed by the supported <b> ones) which makes the generated messages difficultly to read in some notification daemon implementions. Reproducible: Always The launchpad bug page has a trivial patch to fix the issue which I'll try out and attach here if it works.
The patch applied okay, but because it modified a .gob file it caused the build to fail with this error: building server of D-Bus interface org.gnome.MailNotification ERROR: One or more .gob source files were modified but gob2 was not found. Please install gob2 >= 2.0.16 and run configure again. I'll install dev-util/gob temporarily and extend the patch with the changes to the regenerated files to avoid the extra build dependency on dev-util/gob:2.
Created attachment 294323 [details, diff] Proposed fix uses '<b>' tag instead of '<span weight="bold"> This is based on Enrico Scholz's patch in Launchpad: https://bugs.launchpad.net/mail-notification/+bug/799852 https://bugs.launchpad.net/mail-notification/+bug/799852/+attachment/2179334/+files/popup-markup.patch but this patch patches the .c file generated from the .gob file as well (and touches the .gob.stamp file) instead of running 'gob' to do it. With this patch the notifications look fine instead of a garbled mess.
Thanks for doing all the work here :-) Fixed in mail-notification-5.4-r5.
