[Bug 1061101] Re: TypeError: object of type 'NoneType' has no len()

[Marius Gedminas]

Just happened to me.  I created the PPA ~20 minutes ago, then uploaded a
package, waited for it to build, then waited some for it to be
published, then tried to test it and got this error in my teeth.

Is Launchpad generating signing keys asynchronously with some delay?  Do
you have any idea how long that delay might be?  Should I try again in
30 minutes, 1 hour, 1 day?
