Bug#780132: [gedit] Very long line unreadable

[Bzzzz]

Package: gedit
Version: 3.14.0-3
Severity: normal

--- Please enter the report below this line. ---

Hi folks,

A Python program of mine outputs a long dictionary (907k) during
development; when I redirect this output to a file and edit it,
after several pages the rest is mixed up in one line (just like
many lines written on the same one).

Line wrapping on/off doesn't change anything.
