Inkscape crashes when trying to edit text

[Daniel]

Inkscape 0.92.3 (2405546, 2018-03-11)
Fedora 28 x64.

The reproduction steps are very simple, just create a text with a single character, enter select mode, and try to edit it by double clicking it.

I think all these Fedora text issues are related. See also:
https://bugs.launchpad.net/inkscape/+bug/1768958

As I wrote it in https://bugs.launchpad.net/inkscape/+bug/1779779 , for me the crash occurs only if you click on the right half of your single-character text.

Closing as a fix has been committed in 1.0alpha

Note version 0.92.4 in Fedora 28 and 29 (from dnf) doesn't have this problem (perhaps Fix Released is more appropriate); however, I am unsure if a commit was actually added to fix it in 0.92.x.

The commit that fixed it https://gitlab.com/inkscape/inkscape/merge_requests/488

My decision explained in the last three comments in https://bugs.launchpad.net/inkscape/+bug/1768958/

Fedora has applied a downstream patch, but the commits pushed should fix the issue.
