Bug 375987

This bug description includes Erlang (a programming language) and ERTS (it's runtime environment), but I don't think this bug is specific to Erlang, because a quick search leads to http://askubuntu.com/questions/225093/emacs-gives-warnings-in-lubuntu, which is somewhat similar to this bug.

Error message reported by ERTS is:

** (Erlang:13811): WARNING **: Invalid borders specified for theme pixmap: /usr/share/themes/Breeze/gtk-2.0/../assets/line-h.png, borders don't fit within the image
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave

Steps to reproduce:

1) install Erlang, the bug was found on version `Erlang/OTP 18 [erts-7.3.1]`, (archlinux package version 18.3.3-1), but I think the version is not important
2) type `erl` in a shell to start ERTS, the type `observer:start().` to start the observer
3) in the started GUI, click "Table Viewer" tab, then click the "View" menu, the reported message should appear in the shell.
