cpu maxed out in some operations after gtk3 upgrade

[Geoff]

Hi,

This is a preliminary report of an issue that has arisen today and which I have
not had time fully to investigate yet.

Running Arch, my usual full update today was large and included an upgrade
of gtk3 3.12.2-1 -> 3.14.3-2 - which is the usual suspect.

Since the upgrade copying of files from one directory to another is maxing out
one of my two cpu's. The operation seems to complete, but the cpu stays at 100%
until the instance of emelfm2 is killed. The high cpu usage appears under xorg
rather than being attributed to emelfm2 itself.

I have recompiled against the new library, but to no effect. On one occasion,
running emelfm2 from an xterm, emelfm2 crashed with "resource no longer
available".

Midnight here. Will delve more in due course unless someone suggests an easy
fix (said the optimist).

I don't have any debugging symbols in my working emelfm2, but here is the gdb
output of an attempt to copy a batch of files from one directory to another
just now. As before, emelfm2 eventually hung on 100% cpu until I killed it. The
"Busy" indicator was present, but no animation.

Do you need "set solib-search-path" or "set sysroot"?

Ok - this may be theme-related. I will post again only if changing themes does
not yield a permanent fix.
