Short description of error
When trying to move a keyframe in the dope sheet, the program crashed. I reopened the file and tried again, and it crashed again.

Exact steps for others to reproduce the error
open dope sheet, click on keyframe to highlight, press G to grab, as soon as I start moving it, the program crashes.

Based on a (as simple as possible) attached .blend file with minimum amount of steps{F5285757}

Confirm. I've tested the file and also got crash. [version: 2.80 (sub 27), branch: blender2.8, commit date: 2018-10-29 00:08, hash: c750ebe113e, type: Release]

FYI, the same thing happens when selecting multiple keyframes with the B box select. As soon as you trying moving them with G, the program crashes.

I'm actually having a hard time reproducing this (on linux).
I do get warnings about a missing font /c/Windows/Fonts/HLBC___.PFB and a drawing error regarding a curve BezierCircle.001
But I am not getting a crash moving keyframes...

Just out of interest: are you still getting crashes if you remove the fonts and the curves?

Hi, and thanks for attending to this. I disconneted the font and it still crashed, but when I deleted the BezierCircle.001 (which I'm using as a guide to track a camera), moving keyframes no longer crash the program. And I just relinked my text to the HLBC font and moving keyframes still works, so it was definitely something with the bezier circle. As a test, I just added a new BezierCircle and parented my camera to it. When I tried to move a keyframe, the program crashed again.

OK, thx for testing this.
Not sure which keyframes are actually moved [also: is this set up as a path constraint? or follow curve?]

Could you try to reproduce this with just this minimal setup that also crashes? (Camera and Curve or whatever else needs to be in there to get it to crash) and share that .blend here?
Thanx in advance!

I deleted about 90% of the objects from the file, then added a bezier circle and parented a camera to it. I could not get the crash to reproduce itself. It's impossible for me to know what changed, and deleting one object at a time and retesting would take an extremely long time. If I come across anything I think might help, I'll let you know.
