reactivating of irc-account not possible

Binary package hint: gaim

2 similar accounts. Protocol is IRC server is irc.euirc.net. When I leave the Chat via [/quit] the account does not reactivate. When creating a new one with identical values, it works. Activating/Deactivating is possible as long as I quit the chat via shutting down the Window or click [deactivate] in the menu.
When going first way, account->activate will take no effect, when going second way, a window opens immediately an messages are shown.
