Crashes when trying to import webm

[cf8geek]

Describe the bug OpenShot crashes when trying to import webm video(s).

Steps to reproduce the behavior:

1. Click green + button
2. Navigate to a webm video file
3. Double-click on the file
4. OpenShot crashes
5. Try again using shift-click to select multiple, and using [enter] key on keyboard vs clicking "open" button; all yield same behavior (crash)

Expected behavior OpenShot should import the file(s) without crashing.

Is this happening with all Webm videos, or a specific few?

[cf8geek]

All that I have tested. Digging through the GitHub issues it appears it may be bigger than WebM, lots of people appear to be experiencing issues importing videos at all with recent releases (but they didn't show up when I searched before submitting).

(I didn't find an obvious link on the OpenShot website to GitHub; I was only brought here after submitting the bug.)

[FireByTrial]

I downloaded and installed 2.6.0 from GitHub releases, that version was able to import my webm just fine. This was the version I installed on windows: https://github.com/OpenShot/openshot-qt/releases/tag/v2.6.0

before that I tried 2.6.1 and 2.6.1-dev for me both crashed on import.

(edit: add link to release)

@FireByTrial If you have an example of a file that did this, and info on your operating system, and computer, that may help us reproduce this issue, so we can track down the cause.

pelican water landing.webm Same issue, heres the file that crashes it for me

[Colorjet3]

Thank you @claydegruchy I am able to replicate this issue with the latest DEV Daily build v3.0.0 as well in both Windows and Linux. I will be opening an internal ticket to get this resolved. Meanwhile, I was able to run this file through a converter and converted it to .mp4 and I can import it into OpenShot and it works. I used ShutteEncoder but you can also use Handbrake or VLC as well.
