Processing 0148
OS X 10.6, MacBook Pro

Clicking the -> arrow on the tab bar pops up an unpopulated menu. The program hangs. It
seems to be related to drawing text, as I can also induce a crash using the "Create Font"
window when selecting "AppleBraille".

From a sample:

1397 Java_apple_awt_CTextPipe_doDrawString
1397 DrawTextContext
1397 JavaCT_DrawTextUsingQSD
1397 CTLineDrawCharsWithUnicodeProvider
1397 TTypesetterUniChar::TTypesetterUniChar(unsigned short const* (*)(long, long*,
__CFDictionary const**, void*), void (*)(unsigned short const*, void*), void*)
1397 TTypesetter::FinishLayout(TLine&, TCharStream const&) const
1397 TIntegerizationEngine::SnapToIntegerMetrics()
1397 TIntegerizationEngine::SnapRunToIntegerMetrics(TRun&)
1397 CG::round(double)
1397 CG::round(double)

One correlation I have seen between fonts that crash the program is that they are in
/System/Library/Fonts rather than /Library/Fonts or ~/Library/Fonts, but not all fonts in the
former location cause the crash. Some examples that do are Geeza Pro and Zapf Dingbats,
whereas Apple Symbols and Helvetica do not.

I tried with HEAD also and I did not witness any different behavior.

I think something is hosed with the fonts on your machine. That error
message is from far outside the Processing code, so you're either hitting
an Apple Java bug, or (probably more likely) one or several of your fonts
has become corrupt.
