Hello.

Liferea-1.15.2 built on Gentoo doesn't display feed item pane. Here is screenshot:

There are WebKit errors in the console:

(WebKitWebProcess:73007): Gdk-WARNING **: 21:32:56.147: The program 'WebKitWebProcess' received an X Window System error.
This probably reflects a bug in the program.

   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

What was the solution? (just for people who kight come across the same problem)

[nE0sIghT]

It was local problem. I upgraded nvidia-drivers and restarted liferea without restarting PC.
