Bug#958210: libghc-curl-dev: doesn't call the ProgressFunction and doesn't get all of the file

[Brian Sammon]

Package: libghc-curl-dev
Version: 1.3.8-9+b1
Severity: normal

When I run the attached script/program (small, reduced to a test-case) the callback function I register with the "CurlProgressFunction" option doesn't appear to get called.  Additionally the output file "libc6.deb" is smaller than it should be.

When I get a chance, I will upgrade my haskell install and try again with a later version of libghc-curl-dev, although judging by the debian-changelog, it seems unlikely that there will be any difference.

I am a beginner-to-intermediate haskell programmer, so this problem may be due to a mix of user-error and poor documentation for libghc-curl-dev.
