Can't launch Inkscape 0.92+devel ('min-height' causes crash in GTK 3.18)

- could you attach a sample version of the file style.css, one which contains the min-height property?
- could you indicate, or do you remember, which actions you took in the gui that may have introduced this variable?

Hello Alvin.
Here is the style.css attached.
I haven't touched the style.css until the error occurred.
After the error message I've tried to comment out the lines:

 99 /*min-height: 15px;*/
> 137 /*min-width: 0px;*/
> 138 /*min-height: 0px;*/
> 148 /*min-height: 24px;*/
>

and then the program launches without this error.

I don't know if it's relevant, but I also got one alert relating Harfbuzz
(because I am using Mint 18.3 - based on Ubuntu 16.04)

> Requires Harfbuzz 1.2.3 for visualizing alternative glyph OpenType tables.
> Compiled with: 1.0.1.

Thank you for your reply.

PS apologize my poor english.

@Carlos: It seems you're running an unstable development branch of Inkscape (0.92+devel) aka master aka trunk.
If this is not on purpose you should consider to switch to the stable branch (0.92.x), the latest stable version is Inkscape 0.92.2.

The issue you're experiencing was already mentioned at
https://gitlab.com/inkscape/inkscape/commit/032b8d6d039b93824ebd6312ad0a6bdd1ba2ba76#note_52614743
and seems to be a bug in older versions of GTK3. The stable branch still uses GTK2 and is not affected. A solution for the unstable branch has yet to be found.

Thanks Eduard.

Reproduced on Xubuntu 16.04 (GTK 3.18).
Should you change the code so that it also works on old LTS versions (expected to be supported 5 years), or just target more recent Ubuntu versions with more recent GTK libraries? Knowing that 16.04 users still have the 0.92 branch available.

Fixed in
https://gitlab.com/inkscape/inkscape/commit/0d0699f723e09fbf040a32c7cf11a0a50fe7d77a

The regression was accidentally introduced in
https://gitlab.com/inkscape/inkscape/commit/cf457eea72b81850da5503d0091952871135c1fd

GTK+ 3.18 obviously still does not support the min-height property (so some tweaking might still be necessary design-wise), but at least Inkscape should not crash anymore because of that.
