RE: libcurl FTP - directory listing by file mask

Transfer of FTP file consisting of the directory contents would be
perfectly fine with us.
However, the attached app fails with the following error:
/home/sambuild/TESTS/CURL> ./lib525_mget
* About to connect() to geniosol9.hcl.com port 21 (#0)
* Trying 10.3.14.92... * connected

Bus error(coredump)
It looks like data connection cannot be built when NLST is supplied in
CURLOPT_QUOTE list.
As soon as I uncomment curl_easy_setopt(curl, CURLOPT_FTPLISTONLY, 1) it
works just fine, but as one would expect, it transfers the whole
directory.
This is the functionality that I was trying to implement with libcurl:

We have currently implemented FTP functionality w/o libcurl by sending
RFC959 commands via open socket connection. Sending "NLST *.txt" returns
an output identical to 'ls' in built-in client implementation.

That won't work, either, because NLST initiates a FTP file transfer
consisting of the directory contents.
