Bug 437097

SUMMARY

Spectacle 21.04.0 installed from the snap store will not run on Ubuntu 18.04.5 LTS.  When attempting to run, the following error is received:

spectacle: symbol lookup error: /snap/spectacle/136/usr/lib/x86_64-linux-gnu/libKF5KIOWidgets.so.5: undefined symbol: _ZN9KLineEdit16returnKeyPressedERK7QString

Spectacle snaps prior to this version were working fine for me and only started to fail to work after a recent update (possibly before 21.04.0 - I don't have a record of the last working version).

Apologies if this is a local error.  I'm not a snap expert but had assumed that all necessary dependencies should be shipped in the snap package.

STEPS TO REPRODUCE
1. Install spectacle from https://snapcraft.io/spectacle
2. Run the program

OBSERVED RESULT
spectacle: symbol lookup error: /snap/spectacle/136/usr/lib/x86_64-linux-gnu/libKF5KIOWidgets.so.5: undefined symbol: _ZN9KLineEdit16returnKeyPressedERK7QString

EXPECTED RESULT
Program would run

SOFTWARE/OS VERSIONS
Ubuntu 18.04.5 (assuming other software is irrelevant since this relates to the snap version, but please tell me if more info is needed)
