1.1.0 log
I've checked with other versions. ModemManager-1.3.0-2.fc21.i686.rpm and 1.4.4-1 do not work, version 1.2.0-3 works. So the breakage happened between 1.2.0 and 1.3.0. I reported upstream - https://bugs.freedesktop.org/show_bug.cgi?id=89368 Created attachment 997108 [details]
fix
It was fixed upstream. I attach the fix.
Upstream commit - http://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=6a8fbf917a220416913a5e64a40bd4d26c6448f5 Fixed in ModemManager-1.4.6-1.fc22, so I'm closing this. |
