[imp] Trouble importing PGP private key

[Dan Brown]

Using HEAD imp/horde as of last night.  Automatically verifying signed
messages works fine, as does (usually) getting keys from the key server. 
However, I'm unable to import my existing private key.

I'm running GPG 1.2.4 for Windows on my desktop machine at home, and 1.2.4
for Linux on my server.  When I try to import my existing private key from
my desktop machine into IMP (either by pasting it into the text entry field
or by browsing for the file), I get the message at the top of the import
window that importing the key succeeded.  However, the key is not
imported--the PGP options screen doesn't show it there, and still gives the
fields to create a new key.  Returning to the options menu and going back
to that page doesn't change anything.

Don't know if it's relevant, but I'm running PHP 4.3.6 and Apache 1.3.27. 
Any ideas what could be causing this, or is it a known issue?
