liferea is completely invisible when running on xubuntu

Status changed to 'Confirmed' because the bug affects multiple users.

As a temporary workaround, I've made a package for raring which does not have the unity patches (I grabbed the package from Debian): https://launchpad.net/~dtl131/+archive/mediahacks/+packages

It's also broken on enlightenment/e17.

Still broken on 13.10.

Still broken on 14.04 (beta)

And still broken in the 14.04 final release.

I think liferea changed how notification is displayed, I've installed XUbuntu 14.04, and I got envelope icon with liferea inside, and it show all new feeds in a menu. But the icon don't change so you need to click to see if there are new posts.

Still broken on 14.04 three months after release.

Suprise, surprise: still broken in 14.10 beta.

Back to Debian, everything works fine there.

I guess this is why I don't get a panel tray icon on ubuntu MATE

This regression is still present in vivid.

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.)

(Incidentally, this issue does not appear with the MATE/Debian testing system I was using up until a day or two ago and only showed up after switching to Ubuntu.)

Still present in ubuntu 14.04 on august 2015. It appears that the window of liferea won't come up when you click from the top bar menu (where is located thunderbird too). Even from a terminal it doesn't show up.
