Just added Indicator Applet Complete, clicked on Time & Date Settings, Unlock, Clock, Choose Locations, tried to close "Choose Locations" window, then crash happened.

the bug has some duplicates, setting as confirmed

[Karl Lattimer (karl-qdh)]

taking a look at the code that causes this bug now, some changes to the geonames code might have occurred since.

any hints on reproducing this bug, e.g. input methods used, keyboard layout used, language used and location added might help.

Could possibly be bad data from geonames which hasn't been well sanitised.

[Karl Lattimer (karl-qdh)]

this bug is triggered when the system is offline, possibly when some unexpected text is put in the completion entry.

I'd like a sample of the text which causes this bug so I can identify the issue.

I get this bug when online. Language is en-nz, and no completions are shown when typing in any city.

[Karl Lattimer (karl-qdh)]

Looking through mterry's patches yesterday it appears this may be fixed, a lot has changed in the save_and_use_model function.

[David Barth (dbarth)]

Thanks mterry!

I get this trying to add other locations. I check "Show time in other locations", and then "Add locations" (this from memory, not sure of the real texts). A small listbox with "UTC" and a time appears. If I click "+" to add an item, I get an edit control on the left-side of the listbox. There's no completion, no apparent validation, etc. I can enter "India", "ISt", and so forth, and get a crash from doing so.

( indicator-datetime 0.2.0-0ubuntu1 )
Retested here, and problem solved for me, both online and offline. Completion now works, and city addition does not currently crash.

[Michael Terry (mterry)]

Nope, I see what's causing this now. Patch coming.

This bug was fixed in the package indicator-datetime - 0.2.1-0ubuntu1
