If the Show Waveform is enabled for a track and you try to slice it, Opeshot will crash with:

timeline_webview:INFO Generate left splice waveform for clip id: 3WXNT9E102
Unhandled Python exception

It happens every time.

@firew4lker I see that you've been spamming references to your issues in other non-related issues. Please in future issues do not go referencing your issue in others that are not related to the one you have reported. It is spam and I am closing this issue because of it.

We will get to issues as we deem their priority.

[firew4lker]

@jreynojustin Your are being stupid. You ought to read messages and bugs carefully. The hastag (#) followed by a number is the way a stack trace is produced by the debugger.

It Is NOT a reference to another bug.

Now, apologize and Reopen the bug.

[jreynojustin]

@firew4lker,

You should have formatted your post correctly as a code snippet or gist knowing the hashtag symbol referenced other issues.

Anyway, your issue was dated and had to have been from an older version of OpenShot which is also grounds to closing an issue.

Are you still having the issue in the latest build of V2.2?

[ankitpati]

@jreynojustin Collaborators can reformat comments. We should try that before contacting the issue reporters. I just reformatted the comment to remove the # tags.

@firew4lker Can you please verify if the issue persists in the latest stable release?

[firew4lker]

No the problem is NOT present now. But there is another (related?) bug. #518
