EmptyPage: That page number is less than 1

[jyggen]

After upgrading from 5.4.x to 6.4.4 I receive "EmptyPage: That page number is less than 1" while navigating to certain pages.

So far I've encountered it in the following templates (according to the internal logs):

• sentry/groups/group_list.html
• sentry/admin/teams/list.html
• sentry/admin/projects/list.html

Not sure where to start digging. I had some issues with weird styling and javascript errors for a while, but it solved itself.

I ran into the same issue. After upgrading 5.4 > 6.4.4

here the traceback:

I just ran into this issue. Upgrading to django-paging >= 0.2.5 fixes it.

The commit that fixed this: dcramer/django-paging@d6e67d6

[flecno]

Good suggestion. Also the django-paging update is already on master: Cherrypick 578d541 or upgrade with easy_install -U git+https://github.com/flecno/sentry.git

@jyggen i think the issue could be closed

[jyggen]

Right. Thanks guys! :)

[gregwjacobs]

I also can confirm, upgrading to django-paging >= 0.2.5 fix this...
