This is a hang I had with the code from 20.m4.2009, which I could not reproduce anymore. Please ignore it if this was already fixed or the code seems correct. I could get this log of system calls: XftCharIndex(0x8709800, 0x9eb3528, 32, 786432, 8) = 411 XftGlyphExtents(0x8709800, 0x9eb3528, 0xbfb2e05c, 1, 0xbfb2deb8) = 0 XftCharIndex(0x8709800, 0x9eb3528,
