regina-normal crashes on startup

Hello Ben, or anyone else affected,

Accepted regina-normal into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/regina-normal/5.1-2build2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Hi Robie, Logan - thanks for looking after this.

I've tested 5.1-2build2 (amd64) on a bionic machine and this fixes the problem for me.

Checks performed:
- The GUI /usr/bin/regina-gui starts without crashing;
- File -> Open Example -> Introductory Examples loads the sample file correctly;
- The mathematical objects that are stored in this file are displayed correctly when opened in the GUI;
- In particular, graph visualisation works correctly (for instance, double click on "Poincaré Homology Sphere", visit the Skeleton -> Graphs tab, and verify that the GUI displays a complete graph on five vertices);
- The embedded python script at the bottom of the sample file opens and runs correctly.

So everything looks good to me. I will change the tag from verification-needed-bionic to verification-done-bionic.

Best regards - Ben.

Hi - FYI, after rereading the docs, my understanding is that I should change verification-needed to verification-done also, since bionic was the only release that actually needed verifying (and this was done successfully). So I've just done this now. - Ben.

This bug was fixed in the package regina-normal - 5.1-2build2
