some random crash

I've just experienced crash on build 3788 just when I tried refreshing the data tab with the refresh button:

"Continue" button didn't work, I had to restart Heidi. Unfortunately, I couldn't reproduce it. I had 2 db connections open when that happened.

Yes, had that two as I had one mysql + one mssql connection open and the datagrid was loaded. Will check that.

Well, I did nothing ... wrote into a forum.HSQL just ran, connected to one local mySQL DB. HSQL just went into the background - after forwarding, error was already viewable.

I wrote it to this post, because it's also an adress violation. Full report on request ...

Please post the last 10 lines of the callstack please.

I guess, this it is ...

No, please from the 10 lines from the top, not from the bottom. Thanks :)

Last 10 ... first 10 ... what about "next ten after reching middle to nowhere"?! :D

Still wrong?! Hey, come one ... :D

No, this is perfect. GetNetTypeGroup is young small and obviously has some bug. Will check that.

r3793 should fix the crash when switching to a table in another connection. Probably also the one reported by Curanai but I could however never reproduce that one.

If a similar problem will be shown, I'll report it, too! You are doing a great job and bugfixing is fast - keep going, we'll report anything!! :D

Makes me fear about tons of new reports ... hopefully not

HSQL said "bye bye" after "empty table" per right click (alt. menu) in the left panel - this is not (!) the first time ...

Last actions: I made a change on a tinyint (dbl-click value), pressed enter after change, moved cursor down and the log window presented the affected-time and so on - but the change wasn't made (!). I was wondering because of the old view in the browser after hitting refresh - refreshing HSQL, the old value was inside. The shown call stack above is the result of the next step - "empty table" complete. I'll try to do the same again ...
