Just grabbed the latest and pidgin segfaults. With the original .purple directory, I got the following in dmesg:
[ 72.021127] pidgin[3990]: segfault at 7fd99dfaac30 ip 00007fd99dfaac30 sp 00007fffbfe1c618 error 14 in libgvfsdbus.so[7fd99dddd000+1ff000]

After renaming the .purple directory to start fresh, I put in my Google Talk details and got the following:
[ 274.270380] pidgin[4550]: segfault at 7fc399f2cc30 ip 00007fc399f2cc30 sp 00007fffbbd9e568 error 15 in 365b55f210c0a22e9a19e35191240f32-x86-64.cache-2[7fc399f1a000+2e000]

Removed .purple, started fresh. Used a Yahoo account with no issue. Added Google account and it segfaults just after connecting with:
pidgin[4942]: segfault at 7f5b68f86c30 ip 00007f5b68f86c30 sp 00007fff8adf65c8 error 15 in 365b55f210c0a22e9a19e35191240f32-x86-64.cache-2[7f5b68f74000+2e000]
