Breakpad DOES NOT generate a report for this crash.

This doesn't appear to be a regression from 4.0.229.1.  Breakpad doesn't seem to
generate a report for this crash in that build either.

Gmail is not required.  Attempting to drag any image from TextEdit into the content
area of a Chrome window results in an instant browser crash, not caught by Breakpad.
 CrashReporter does pick this one up.

Here are some bits from CrashReporter:

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Crashed Thread:  0  Dispatch queue: com.apple.main-thread

Application Specific Information:
abort() called

Breakpad doesn't pick this up because it doesn't listen for EXC_CRASH, corresponding
to abort().  It only picks up EXC_BAD_ACCESS, EXC_BAD_INSTRUCTION, EXC_ARITHMETIC,
and EXC_BREAKPOINT.

I filed http://code.google.com/p/google-breakpad/issues/detail?id=343 for Breakpad.

Additional information follows.

This is logged:

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct NULL not valid
Abort trap

Re comment 5, this bug has nothing to do with gmail, it's just a handy page to be on.

Mark, that's correct. I just mentioned GMail as an example where image dragging 
feature is useful.

be NULL, which throws and exception.
