Check if a changelog was returned, before showing it (prevents a NULL dereference).

Subscribed the listed maintainer to hopefully get this patch added.

[Michael Vogt (mvo)]

Sorry that this came to my attention so late :/

[Michael Vogt (mvo)]

I'm afraid it is too late for this now for dapper, I'll upload it as soon as edgy opens.

  This bug has been fixed in Debian for ages (since last year); the
Ubuntu packages are the responsibility of the Ubuntu maintainer.

Daniel, sorry for this. Feel free to unsubscribe from the report. I'll update the packages immediately once edgy is available.

  And I apologize if my last mail sounded a bit "short" (in both senses)
-- I've been writing to conserve time because I don't have regular network
access. That should be fixed next week when my Internet service is finally
hooked up, though :-)

[Yuriy Kozlov (yuriy-kozlov)]

This hasn't been fixed in edgy.

[Matti Lindell (mlind)]

This should be fixed now on Edgy, aptitude 0.4.1-1.1ubuntu5.

[Yuriy Kozlov (yuriy-kozlov)]

I still (or again?) get a segfault when checking a changelog for a package without candidates with aptitude. Both in Edgy and in Feisty with latest updates.

[Brian Murray (brian-murray)]

I am unable to reproduce this on the final version of Feisty Fawn with aptitude version 0.4.4-1ubuntu3. Is this still an issue for you Yuriy?

[Yuriy Kozlov (yuriy-kozlov)]

Looks fixed.

[Zorael (zorael)]

Still happens in Hardy, on a 64-bit installation. Regression?

I've been unable to recreate this crash using aptitude version 0.4.9-2ubuntu5 from Hardy Heron. I receive the following output:
