Comment(by SgtPepper):

 Small amendment:

 Due to an "inconsistency"* in how Pidgin handles its settings, I've added
 a check for an empty string along with the check for a null pointer.

 * If a setting is empty when Pidgin launches, purple_account_get_string
 returns NULL (the default value).  If the user sets (or has it set on
 launch) a setting then changes it back to empty, purple_account_get_string
 returns "" (empty string).  This is, in my opinion, a bug, but I'll just
 work around it here.
