Subject: Attemp to fix ctrl-c crashes - disconnect from services before calling daemons_stop... 
X-Git-Tag: initial-import-from-subversion-38251~14913
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=def7109bb2daa04027c2de91883486f509f39849;p=oweals%2Fgnunet.git

Attemp to fix ctrl-c crashes - disconnect from services before calling daemons_stop, since the cfg is free'd in the latter.
