When no photos are displayed, clicking on timeline crashes f-spot

Thanks for the report Martin, but that's not a bug here with Jaunty, i get a No matching photos found message on the search bar and clicking on the timeline doens't make the app crash, could you please test with it on jaunty?.

David, can you please post a recipe that includes a timeline click for crashing the Jaunty version?

Sorry I haven't done this sooner; I've been sidetracked by other things.

This recipe crashes it for me:
  1. Start without pre-existing f-spot configuration (no ~/Photos, ~/.gnome2/f-spot or ~/.gconf/apps/f-spot directory).
  2. Start f-spot
  3. In the import dialog which appears, select a directory with some images and import them.
  4. Click the close button in the search bar thingy (the brown bar where it says "import roll")
  5. Double-click a tag which has no photos (none of the photos I imported had any tags so this was trivial)
  6. Maximise the window
  7. Click in the timeline pane.

At this point f-spot seems to crash reliably for me. If I leave out step (6), it doesn't always seem to crash, however it also doesn't seem to respond at all to the click in the timeline pane and clicking there repeatedly does generally seem to crash it.

Running the above recipe starting f-spot from a terminal, I get these messages:

Confirmed, with the steps given on the last comment by David.

found an upstream report with similar trace and steps to reproduce it here: http://bugzilla.gnome.org/show_bug.cgi?id=578871 ; feel free to subscribe. linking the report, thanks both!.

The bug has been fixed upstream, thanks for reporting.

Still present in f-spot 0.6.1.2 (shipped with Karmic)

On a new install - when no photos added -> klick on the timeline slider -> crash

Both bugs here are fixed in 0.6.1.5, in Lucid. The timeline slider is now insensitive when there are no matching images.
