Linux mint electrum trouble

[Rsolo85]

when i install or just start electrum on LM, its crashes with segmentation error (if i configure it in russian rubles)

[Rsolo85]

maybe some different reason

[AbdussamadA]

which version is this? and can you run it via the command line with the -v options i.e. electrum -v and paste bin the output?

[ecdsa]

what does the last line mean? is that a segmentation fault?

[Rsolo85]

yes

[SomberNight]

possibly related #3660

[Perlover]

I am author of 3660 issue

I run electrum with '-v' option and i got segmentation fault after "on_update" too
My output is there: #3660

[Perlover]

@Rsolo85 , can you get "gdb" backtrace?
I did same:

$ ulimit -c unlimited
$ electrum

After crash and in home directory there will be "core" file
Next:

$ cd
$ gdb -c core $(which python3)

and in gdb enter "bt" and
After please send here backtrace

Thsnks!

[Perlover]

Can you try to send a full dump info? You dump it's not full - there are only first lines of backtrace.
May be you need press because your gdb splits long output to pages and Enter can be used for page listing. Or you can try other:

$ gdb -c core $(which python3) |& tee 1.txt

And after exiting from gdb your the 1.txt file will consist dump info

Thanks!

Thanks!
By backtrace it's same problem as issue #3660
I hope the developers of Electrum will patch it. For my issue they told that looks like not Electrum problem.

[outhud]

Hi @Perlover and @Rsolo85

I'm seeing the same problem. Linux Mint 18.3 with Cinnamon 3.6.7, using Electrum-LTC 3.1.3.1

The verbose electrum-ltc output seems to have similar items to you right before the seg fault (removed some bits that looked like wallet addresses):

Segmentation fault

Usually it crashes a few seconds after opening the main window. Did you have any luck solving this?

Hi,
No, i don't have.
I have the computers with Linux Mint. In two computers Electrum crashes but one computer has stability Electrum. I don't understand difference. All libraries are standard from packages excluding the Trezor plugin for python and some related plugins for it (usb hid plugin for example)
