Hello Daniel,

Thank you for asking. There aren't any special chars in the props and I can reproduce this crash with other dumpfiles as well. I do however took a
look at the trunk development of svndumpfilter and got curios about rev 23494.

[svndumpfilter: don't use '%n' in printf strings.

In VS2005, Microsoft has deprecated the use of %n as 'inherently
insecure' and turning it back on requires a special function call.

* subversion/svndumpfilter/main.c
   (write_prop_to_stringbuf, output_revision, output_node): Use the return
     value of sprintf() to determine how many characters were written, rather
     than using '%n' at the end of the string.]

After applying this revision to 1.4.4 everything works as expected with svndumpfilter build against libintl 0.14.6 VC8 build. So I would like to ask
if rev23494 can be backported to 1.4.x.
