[Bug 1525293] Re: "window->screen()->physicalDotsPerInch() / 25.4" may be negative on xenial

 

This is on xenial only, using the latest UITK, and seen in the address-
book-app's contact_list unit test as described in bug #1525174 if
https://code.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-
toolkit/validDpi/+merge/280312 is not applied in UI Toolkit.

Notably this may have something to do with the Qt 5.5 landing also as I
guess it'd be unlikely for any UI Toolkit change itself to cause that
(but it blocked UITK landing until the workaround was implemented).
Xenial images starting this week now have Qt 5.5.

** Description changed:

- [tentative bug report to not forget about it]
+ Window->screen()->physicalDotsPerInch() / 25.4 can be negative on Xenial
+ when using the latest UI Toolkit.
  
- see bug #1525174
+ (see bug #1525174 for original finding)
