Crash pasting an image

• Mar 5, 2021 - 04:07

Figured I'd mention quickly that I copied an image from an image editor, switched over to MuseScore, [ctrl+v]'d without thinking, and got a crash.

I think I had a [title text] within a [vertical frame] selected. As much as that isn't advisable behavior, it obviously shouldn't crash the program. Probably something to do with measure bases versus measures or something while getting the parent.

Hi, i got a crash when pasting an image to a key signature.

All ok when i paste an image to the title frame.

Hmm, now can...

Please report in the issue tracker

In Debug mode it dies on a failed assertion, trying to convert the image to a keysig?

Fatal: ASSERT: "e == 0 || e->isKeySig()" in file ...\libmscore\scoreElement.h, line 520

Doing the same thing onto a title text gives another failed assertion:

Fatal: ASSERT: "ted" in file ...\libmscore\textbase.cpp, line 3052

Fir for the latter is quite simple:

$ git diff
diff --git a/libmscore/textbase.cpp b/libmscore/textbase.cpp
index 31daa8325..f5290cd06 100644
