[Shotwell] Does not register camera on Slackware: Kodak EasyShare CX7430

[Brad Hermanson]

I compiled Shotwell 0.11.1 (and 0.11) on Slackware 13.37 and everything 
went well except for the fact that it does not fully detect my camera 
(Kodak EasyShare CX7430). It never shows up on the side bar. I took a 
look at the logs and found this:

I didn't look too deeply into the code, but I put together a patch that 
fixed the problem (at least for me.. I don't know what ramifications it 
would have on others). Maybe something isn't configured correctly on my 
system, but I'm hoping someone knows why this is happening.

Here is the patch:

          if (port == "usb:") {
              debug("USB ESP: Skipping %s", port);

After adding this patch, the log file shows:

This fixes the problem for me and then the camera shows up and I can 
download photos, etc, and everything works as expected. This same camera 
with shotwell on a recent version of Ubuntu works perfectly fine... I'm 
not sure what to make of it. I don't know if Ubuntu has patched 
Shotwell, or if they simply have something configured differently. I'm 
going to be making the package available for Slackware users, so if this 
is a Slackware-specific problem, any hints as to what I've not 
configured/configured incorrectly would be greatly appreciated.

Thank you,
Brad
