Subject: Support older versions of pyxdg
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a55bec19e4f88bf38d7fb957bf12f9bd63862992;p=mutt-ldap.git

Support older versions of pyxdg

save_cache_path was added in 0.21
See: https://bugs.freedesktop.org/show_bug.cgi?id=26458

Fall back to ~/.cache and make sure the directory exists
(that's what save_cache_path does)
