The TP_CHANNEL_GROUP_CHANGE_REASON_RENAMED signal is not trigered when, i.e. I change my nick from csoriano to Csoriano or backwards. We need this to solve https://bugzilla.gnome.org/show_bug.cgi?id=709439 in Polari application of Gnome.
This isn't a bug, please watch yourself and other contacts for AliasChanged instead (or as well). Renamed, SelfHandleChanged and MembersChangedDetailed(...GROUP_CHANGE_REASON_RENAMED) are only emitted when you change your unique identifier, which on IRC is the normalized (lower-case) form of your nickname. For instance, if you're Csoriano, "/nick C_soriano" would change your alias to C_soriano and your identifier to c_soriano. (This is more complicated than IRC needs, but in most IM protocols, aliases and unique identifiers are independent; also, UIs can't be expected to know how to normalize all protocols' unique identifiers.)
