Sentry Crash Report:

Description nyanpasu64 2020-05-17 17:30:21 UTC 
Application: kontact (5.14.0 (20.04.0))

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 5.6.12-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
## Steps

- Delete or backup ~/.config/kmail2rc. This issue only occurs on fresh launches without this file present.
- Launch Kontact.
- On the "Another mailer was found on system. Do you want to import data from it?" dialog, say No.

## Results

Two Kontact windows pop up. On first launch, neither was logged into Gmail. If you're logged into Gmail, the Kontact window is displaying an email "Welcome to KMail", and "Kontact <2>" is logged into Gmail.

On top of the "Welcome to KMail" Kontact window, a "Enable Unified Mailboxes" modal dialog pops up. Click Cancel.

Account Assistant also pops up. You can close or ignore it.

The "Kontact" window is unstable. Opening settings, or closing the window, crashes both Kontact windows.

Closing "Kontact <2>" doesn't seem to cause issues.

## Notes

Launching KMail after deleting kmail2rc behaves nearly the same, with the excessive number of popups. The only differences are that the "Kontact <2>" window never shows up, the "Kontact" window is called KMail instead of Kontact, and that window is stable and non-crashing.

I think the number of popups negatively affects the Kontact/KMail first-user experience. I'm not sure if "Enable Unified Mailboxes" pops up before or after logging into Gmail. Which is weird since I have 0 or 1 email accounts set up, to my knowledge. How do I find a list of email accounts KDE knows about?

The crash does not seem to be reproducible.
