Reproduced by at least two other people, including me.
I got it using:
- GTK+ 2.16
- GHC 6.10
- gtk2hs is 0.12.2
- TS 0.2.1
I think the other chap was using a more recent GTK and GHC, but probably same gtk2hs and TS.
I narrowed the problem down to this block in GUI.Timeline.Ticks.drawXTicks
when (atMajorTick || atMidTick || tickWidthInPixels > 70) $ do
tExtent <- textExtents tickTimeText
let tExtentWidth = textExtentsWidth tExtent
move_to textPos
m <- getMatrix
identityMatrix
when (floor (pos + incr) <= endPos
&& (tExtentWidth + tExtentWidth / 3 < width || atMajorTick)) $
showText tickTimeText
setMatrix mI didn't get the detailed runtime error message about GetGlyphIndicesW, but I presume that's just a GTK version difference. So it looks like a text rendering issue.
I wonder if it's due to using a large scaling factor in the cairo context.

TS (with widgetSetCanFocus commented out, see #21) crashes under Windows 7 every time an eventlog is loaded.
Backtrace is:
Versions: Haskell Platform is 2011.4.0.0, gtk2hs is 0.12.2, TS is 0.2.1 and GTK is 2.24.8. Look system-specific and was not reproduced with any other GTK version or on any other system, hence the minor priority.
Gtk2hs was installed without any problems, demos were compiled and launched succesfully.
