I am seeing the same thing on Fedora 9.
Sorry, that comment wasn't the most useful. I can see this on a completely up-to-date x86-64 Fedora 9. I also see it if I reboot with a pristine x86-64 Fedora 9 Live CD.

Apparently if a read() of the camera fails due to an interrupt, the library takes this a
a fatal error, and doesn't recover.

This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
On Fedora 10, with all updates, running Gnome, plugging in the camera usually leads to a window saying: Unable to mount Canon, Inc. PowerShot A510 (normal mode) / PowerShot A510 (PTP mode) Error initialising camera: -1: Unspecified error Occasionally (when I plug the camera in) gthumb launches, and crashes in the "Import Photos" window when I try to choose the Destination. Sometimes I plug the camera in, and get asked which application I want. When this happens, gthumb then seems to work properly. Obviously, there's something random going on here, so it's difficult to say that something *always* works. But gphoto2 --get-all-files seems to work reliably. I no longer have Fedora 9 installed.
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
