I can confirm this is still present on a fresh install of vivid/15.04 with MATE & liferea package 1.10.12-1ubuntu1.
On initial launch, Liferea just seems to hang and in `strace` it is stuck in a loop (`top` indicating <1% CPU usage) at recvmsg(7, {msg_name(0)=NULL, msg_iov(1)=[{"U\2;\1SP]\3\3\20\0\0\20\0\0\0\0\0\0\20\20\20\20\20\0\0\3\37\205\3\0\0", 4096}], msg_controllen=0, msg_flags=0}, 0) = 32 recvmsg(7, 0x7ffd814d5550, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(7, 0x7ffd814d5530, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=5, events=POLLIN}, {fd=7, events=POLLIN}, {fd=16, events=POLLIN}], 4, 3654) = 1 ([{fd=7, revents=POLLIN}]) recvmsg(7, {msg_name(0)=NULL, msg_iov(1)=[{"U\2;\1@R]\3\3\24\4\0\20\0\0\0\0\0\0\24\24\24\24\24\0\0\3\37B\2\0\0", 4096}], msg_controllen=0, msg_flags=0}, 0) = 32 recvmsg(7, 0x7ffd814d5550, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(7, 0x7ffd814d5530, 0) = -1 EAGAIN (Resource temporarily unavailable) However, if forced to show using `liferea --mainwindow-state="shown"`, then it appears. (Subsequent invocations also need `--mainwindow-state` as well, it seems.) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to liferea in Ubuntu. https://bugs.launchpad.net/bugs/1186801 Title: liferea is completely invisible when running on xubuntu Status in liferea package in Ubuntu: Triaged Bug description: The patch recently applied to liferea for Unity messaging menu support (port-to-messaging-menu.patch) broke liferea on xubuntu. It eliminated liferea's system tray icon, thereby making liferea inaccessible in xfce when running minimized or started in a minimized state (as is the case for most people who let it auto-start at login time).
