Bug#1004469: yamllint: Dies with a TypeError

[Uwe Kleine-König]

Package: yamllint
Version: 1.26.3-1
Severity: normal

Hello,

$ cat l.yaml
---
mylist:
- |
blablub
};
$ yamllint l.yaml
Traceback (most recent call last):
File "/usr/bin/yamllint", line 33, in <module>
sys.exit(load_entry_point('yamllint==1.26.3', 'console_scripts', 'yamllint')())

'wrong indentation: expected %d but found %d' %
TypeError: %d format: a number is required, not NoneType

I guess the right thing to do would be to output something like:

l.yaml
5:5 error syntax error: expected <block end>, but found '}' (syntax)

(At least this is what happens if I force expected to be a number in
/usr/lib/python3/dist-packages/yamllint/rules/indentation.py", line 346)

Best regards
Uwe
