I think this might be a bug that was fixed after Ethereal 0.9.15 was
released.
If you can compile Ethereal from source, either try the current CVS
version (which requires that you have a bunch of stuff such as autoconf,
automake, Perl, Python, etc. installed) or apply the attached patch to
0.9.15's "epan/tvbuff.c", recompile, and try that.
The capture file is probably in "/tmp" or "/var/tmp", with a name
beginning with "ether" and having a bunch of letters and/or numbers
after it.
