Me dijeron en la lista inglesa que preguntase en http://forums.mozillazine.org/viewforum.php?f=31. Antes de hacerlo me estuve leyendo el FAQ. http://forums.mozillazine.org/viewtopic.php?f=39&t=366405 How to get help (FAQ) http://kb.mozillazine.org/Profile_backup Profile backup Que consiste basicamente en copiarlo todo, lo que reproduciría el error. Pero uno de los enlaces llevaba a: http://kb.mozillazine.org/Profile_folder_-_Thunderbird Profile folder - Thunderbird donde describen que hace cada uno de los ficheros, y mencionaba unos cuantos que se pueden borrar para arreglar errores: - downloads.rdf Download history. Can be deleted to resolve slow downloads or program hangs No lo tengo. - extensions.rdf Installed extension information. It can be deleted to remove "ghost" entries from the extension list and to resolve various other issues. - localstore.rdf Toolbar and window layout size/position settings. It can be deleted to resolve various issues. - mimeTypes.rdf Action to perform when downloading certain types of files. Can be deleted to reset download actions. - panacea.dat Mail folder cache. Deleting it sometimes helps get rid of Phantom folders Y funcionó, borré todos esos. :-))) -- Cheers / Saludos, Carlos E. R. (from 11.2 x86_64 "Emerald" GM (Elessar))
