I've (hopefully) resolved both issues here in SVN revision 24595.  It 
was indirectly caused by the custom column features being added.  It 
actually had to do with a way to store col_expr and col_expr_val data in 
fdata in addition to cf->cinfo so we didn't have to re-dissect every time 
Apply/Prepare a[s] Filter was used, which was a recent fix of mine to 
prevent the custom column's col_expr and col_expr_val from being wiped 
out by repeated epan dissect runs.  I wasn't thinking straight recently 
and I copied and pasted some memory allocations from another part of the 
code so it was allocating memory for strings instead of pointers like 
crazy.  Oops :).

Could you try it and let me know that it's fixed or not?
