gwibber 2.29.94 crashed with NameError in <lambda>()

[GaryW]

Binary package hint: gwibber

NameError: free variable 'about_dialog' referenced before assignment in enclosing scope

Running Ubuntu Lucid Beta fully updated as at today 6th April

This bug first appeared in Lucid Alpha it seems ( #533463 ) and was reported as fixed, but
in today fully updated system I encountered this issue.

Reference was also made in comments to an even earlier appearance of this bug
  ( https://bugs.launchpad.net/bugs/346336 )

Bug #533463 was marked 'fix released', I think based on non-appearance rather than a specific
investigation of cause and code change - apologies if I am wrong in my reading of this.

Might be that the 'About Gwibber' functionality needs looking at as the 'Close' button would not
work and I had to manually exit with the cross (X) icon. This might be a symptom of this bug or
some other problem with functionality.

This crash has the same stack trace characteristics as bug #533463. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

@GaryW, Please could you run under latest version of gwibber: gwibber --debug > gwibber-debug.log and attach output to your report (following your steps to reproduce this issue), Thanks!

Version is 2.29.95 now and @Kamus I did not see any problems when using the 'Help/About' function of Gwibber :)

If the "free variable 'about_dialog'" bug does not reappear by Ubuntu Lucid final release then it would seem that the bug I experienced in 2.29.94 may have been fixed in the new code of 2.29.95

I do not have the knowledge to say whether any of the messages marked "** (gwibber:3290):" above are serious enough to warrant bug reports, although the last one marked critical might be worthy of a look.

Gwibber is a great tool for Ubuntu Lucid, and I am sure it will be well received, when the final release is issued late April.

I received this error after updating to today's Gwibber package updates.

[Nizar Kerkeni (nizarus)]

same bug with Gwibber 2.30.0.1

[Victor Vargas (kamus)]

@GaryW, is this issue still affecting under gwibber 2.30.0.1-0ubuntu3?

[GaryW (gnubyexample)]

@Kamus, my system is just updated (see supporting below) at today May 12th, and starting up Gwibber, I see no repeat of the original bug.

From within Gwibber I was able to view the full tweet and it opened in an external browser just fine.

No crashes experienced during my session.

No problems for me in opening 'About Gwibber' dialog and closing it again.
