galeon 1.3.11a is out (1.3.11 was buggy and shouldn't be used). Copying the ebuild and removing the galeon-1.3.10-gcc2_fixes.patch works. About the patch: No idea why it was added, it is not mentioned in the changelog and i don't know if it has been sent upstream.
The name is obvious, it fixes gcc2 issues. A quick peek at the code reveals this got fixed. Just added 1.3.11a
