With a

If nobody else can reproduce this, then I'll try a stock

But, with SVN r49098, I get lots of the

** (tshark.exe:3668): WARNING **:

On "release" 1.8.6, WinXP 32 and Win 7 64-bit I get no errors.
On "release" 1.10rc1 Win 7 64-bit I get no errors
On SVN 49091 + some (unrelated) local modifications (WinXP 32-bit), I get the
errors Chris mentioned about unregistered hfs. No _DIVIDE_BY_ZERO warnings
(original bug reported)
Little surprised this is only on the trunk, would have expected it to make it
into 1.10.
