When opening the command window via ':', no text keys are detected. Cursor movements, control characters, and tab are detected though. The same is true for search ('/' and '?'). Strangely after tab is pressed, text keys are recognized, but only until the command window is opened again. A bug has been filed (http://bugs.pwmt.org/issue513), but given that gentoo portage is common between the two issues, it seems possible it may be portage specific. The version is 0.3.3.
Your url is dead. Is this the bug report you're talking about: https://bugs.pwmt.org/project/zathura/issue/469 ?
It works if i build girara by hand.
Okay, girara is allergic to clang. CC=gcc fixed the problem.
should be fixed
