I thank you highly for this nice widget but excuse me.
If empty space in folder name triggers bug that makes recaller not stop. THEN IMO it really should be demoted from extra to testing.

I do not know how much you spend time here around TMO, but I see too many noobs end up here and have problems with their N900 which has slowed down. Some of them seem to have problem with Recaller (and some poor souls have enabled devel & testing without knowing what they are doing) and they should not have to read download page comments or maemo wiki page comments. Well why? Because it´s from extra repository. Repository that should represent the highest quality of maemo.org applications. It´s enabled by default on N900 and people do who install stuff from there probably do not have slightest idea what maemo.org or TMO is.

Still great app and hopefully you are fixing it soonish.
