Thank you for the quick feedback.

I tried that, but without success:

$ mv .cache/font-manager .tmp-font-manager
$ font-manager
(font-manager:84688): Gtk-WARNING **: 14:48:38.294: GtkGizmo 0x56343141bfa0 
(progress) reported min width -2, but sizes must be >= 0
(font-manager:84688): [font-manager]-WARNING **: 14:48:39.154: SQLite Result 
Code 0 : not an error
**
[font-manager]:ERROR:../lib/common/font-manager-database.c:631:update_available_fonts:
 assertion failed: (sqlite3_step_succeeded(db, SQLITE_DONE))
Bail out! 
[font-manager]:ERROR:../lib/common/font-manager-database.c:631:update_available_fonts:
 assertion failed: (sqlite3_step_succeeded(db, SQLITE_DONE))
Aborted

I never started font-manager successfully on that machine. The error occurred 
even immediately after installing font-manager.

Should I send the font-manager cache directory anyway?

Just to rule out other possibilities, can you try to create
a *new* user and launch the font-manager tool right away
after the first new user login?

If you have time, you may also try to install a new Debian OS
with virtual machine and try again.

I cannot reproduce your issue anywhere, so we must rule
out the possibility of issues on your specific machine first.

Thanks,
Boyuan

Dear Maintainer,

font-manager crashes immediately after startup. Two windows are visible for a
split-second before the crash, one of them showing a font in varios sizes.

Whenn executing font-manager from a terminal emulator, I can see these error
messages:
$ font-manager
(font-manager:54421): Gtk-WARNING **: 08:09:00.992: GtkGizmo 0x55daccdb4510

Can you try the following steps:

1. Backup your ~/.cache/font-manager/ directory.
2. Remove your ~/.cache/font-manager/ directory completely.
3. Reboot and restart font-manager tool to see if anything changes.

If font-manager could be launched successfully with the 3 steps above,
that means your cached database has been damaged. It could be due to unsafe
system reboots while the font-manager is opened, or that your hard disk is 
failing.

In that case, could you send me your old ~/.cache/font-manager/ directory?
I can hand that to font-manager upstream and let them know that a broken
sqlite database could prevent font-manager from launching without failsafe.
Or you could make the bug report upstream by yourself.

Thanks,
Boyuan Yang
