fontforge crashing/exiting when I import SVG file

[powerab]

macOS Sierra
Version 10.12.6

I have downloaded the app + Quartz today and having issues when importing the SVG file. I click on a glyph to import the SVG file, but when I do, the entire app crashes/exits.

Also when I click on the glyph window, the grid isn't showing.

Any way I can fix this?

By Grid do you mean the lines that go horizontal and vertical?

If so, you create those yourself by dragging from the ruler. They are then editable in the Guide layer. I recommend making sure to align them to int. To do so follow these steps.

1. Make sure you're in the Guide Layer and Select All points with ctrl + a (cmd + a on Mac), if that doesn't work, Edit > Select > Select All.
2. Now press ctrl + shift + _ (cmd + shift + _ on Mac) If that doesn't work, Element > Round > To Int. This step will actually align the Guide to Int.

Whatever is in the Guide Layer, will show through all other Glyphs. All other layers are exclusive.

As for the Crashing part, can you run FontForge through the Terminal and let us know what output you get during after the crash?

The only other thing I can recommend is making sure you have the proper libraries installed. But I'm not sure as to how that works or even if that could be an issue on Mac as I use Linux.

Sample please

This is a single "o" glyph created using Inkscape (+typography tools extensions). Saved as a "Plain SVG".

Attempting to import this consistently crashes FF on Win10.

@patdavid I've confirmed the bug you found. It's happening (as I expected) because of the embedded image you have in the file.

Quick workaround: Remove image.
Long-term change: Fix the underlying issue in DecodeBase64ToFile.

@skef Just wanted to commend you for the work you've been doing fixing bugs, both previously verified and unverified. You're awesome and the work you're doing is greatly appreciated!
